Basic Maintenance
Warning
To avoid shock, remove the test leads and any input signals before opening
the case or replacing the battery or fuses.
Opening the Meter Case
Caution
To avoid unintentional short circuit, always place the uncovered Meter
assembly on a protective surface. When the case of the Meter is open, circuit
connections are exposed.
To open the Meter case, refer to Figure 1 and do the following:
1. Disconnect test leads from any live source, turn the rotary switch to OFF, and remove the
test leads from the front terminals.
2. Remove the battery door by using a Phillips-head screwdriver to remove the screw to the
battery door.
3. The case bottom is secured to the case top by three screws and two internal snaps
(at the LCD end). Use a Phillips-head screwdriver to remove the three screws.
4. Un-snap the Battery and table the battery snap out of the battery room.
Note
The gasket between the two case halves is sealed to, and must remain with, the case bottom. The case top lifts
away from the gasket easily. Do not damage the gasket or attempt to separate the case bottom from the gasket.
5. Hold the Meter display side up.
6. Lifting up on the input terminal end, disengage the case top from the gasket.
7. Gently unsnap the case top at the display end.
Battery Replacement (refer to Figure 1)
1. Disconnect the test leads from any circuit under test and turn off meter.
2. Remove the test leads from meter.
3. Loosen the screw from the battery cover on bottom case.
4. Remove battery cover.
5. Install a new battery after removing the original one.
6. Assemble battery cover onto bottom case with screwdriver and the screw
described in step 3.
Testing Fuses (FS1 and FS2)
To test the internal fuses of the Meter, refer to Figure 1 and do the following:
1. Turn the rotary selector switch to the mA position for 1A fuse test FS1 or A
position for 15A fuse test FS2.
2. To test FS1, plug a test lead into mA input terminal, and turn the rotary selector to the
mA position.
2.1 Fuse is OK if display shows normal functional graphics.
2.2 Fuse is defective if “FUSE” is displayed, and the built-in beeper alarms.
3. To test FS2, plug a test lead into A input terminal, and turn the rotary selector to the
A position.
3.1 Fuse is OK if the display shows normal functional graphics
3.2 Fuse is defective if “FUSE” is displayed, and the built-in beeper alarms.

Replacing Fuses
Warning
To avoid electrical shock, remove the test leads and any input signals before
replacing the battery or fuses. To prevent damage or injury, INSTALL ONLY
quick acting fuses with the following Amp/Volt current interrupt rating:
FS1 Fuse: 1A, 600V, FAST. Minimum interrupt rating 10,000A
FS2 Fuse: 15A, 600V, FAST. Minimum interrupt rating 100,000A
To replace the Meter’s fuses, refer to Figure 1 and do the following:
1. Follow step 1 to step 4 described in Battery Replacement.
2. Remove the battery from meter.
3. Remove 4 screws installed between the top case and bottom case of meter.
4. Separate bottom case from Meter, using care not damage battery wiring.
5. Remove 4 screws installed between the PCB and top case of meter.
6. Separate the PCB from the top case of Meter.
7. Replace a new fuse (FUSE 1 or FUSE 2).
8. Re-assemble the PCB with the top case of Meter.
9. Assemble the bottom case to top case using care not to damage battery wiring.
10. Install the battery removed before and re-assemble the battery cover.
Cleaning
Warning
To avoid electrical shock or damage to the Meter, never allow
water inside the case. To avoid damaging the Meter’s housing,
never apply solvents to the Meter.
Input Terminals
Water, dirt, or other contamination in the A or mA input terminals may activate the Input Alert beeper even
though test leads are not inserted. Such contamination might be dislodged by turning the Meter over and, with all
test leads removed, gently tapping on the case.
To clean the input terminals, do the following:
1. Turn the Meter off and remove all test leads from the terminals.
2. Use a clean swab in each of the four terminals to dislodge and cleanout the
contamination.
3. Moisten a new swab with a cleaning and oiling agent work this swab around in each of
the four terminals. The oiling agent insulates the terminals from moisture related shorting
and ensures against false Input Alerts.

Performance Tests
The following performance tests verify the complete operability of the
Meter and check the accuracy of each Meter function against the Meter’s specifications.
Accuracy specifications are valid for a period of one year after calibration, when measured at an operating
temperature of 18°C to 28°C and at a maximum of 80% relative humidity.
To perform the following tests, it is not necessary to open the case; no adjustments are necessary. Merely
make the required connections, apply the designated inputs, and determine if the reading on the Meter display
falls within the acceptable range indicated.
If the Meter fails any of these tests, it needs calibration adjustment or repair.
The performance data in the following tables are in 40,000 count display mode.
In 4000 count mode disregard the less significant digit.
A Basic Operability Test
To check the basic operability do the following:
1. Turn the rotary switch to A and plug a test leads into A input terminal.
Unit display is of normal functional graphics if the fuse is good.
2. Turn the rotary switch to mA input fuse (1A) insert a test lead into the mA input
terminal. (A input must be cleared of connections).
Unit display is of normal functional graphics if the fuse is good.
If the Meter fails to operate properly:
• Check the battery and fuses and replace as needed.
• Verify that you are operating the Meter correctly by reviewing the operation
instructions found in the Users Manual.
To complete a comprehensive performance test and verify the accuracy of each Meter function and operation,
perform the remainder of the tests under “ Performance Tests ”.
Testing the Display
Press and hold the “Bar” key while turning the unit ON to enter the Display Hold Mode function. Compare the
display with the appropriate example in Figure 2.
Turn off the meter to escape the Display Hold Mode.

Testing the Voltage Function
To verify accuracy in the DC and AC voltage ranges, do the following:
1. Connect the Calibrator to the VΩ and COM inputs on the Meter.
2. Set the Calibrator for the voltage from step 1 to 5 in Table 1.
Compare the reading on the Meter display with the display reading shown in Table 1.
If the display reading falls outside of the range shown in Table 1, the Meter does not
meet specification.

Testing the Capacitance Function
The Meter measures capacitance by charging the capacitor with a known direct current, and measuring the
resultant voltage, and calculating the capacitance. If the same capacitance is measured on an impedance bridge, a
different reading may result. This variance is likely to be greater at higher frequencies.
To verify the accuracy of the capacitance measuring function, do the following:
1. Apply the Capacitor to the VΩ and COM inputs on the Meter.
2. For steps 1 through 8 in Table 7.
a) Turn the rotary switch
b) Set the VΩ and COM inputs un-connected
c) Select Δ or (REL) for steps 1 and 2 in Table 7. After steps 1 and 2 are complete, escape
from Δ mode and press (RANGE) key until (AUTO) is displayed.

Calibration:
Calibration of the meter is recommended once a year to ensure performance according to the published
specifications.
Calibration is performed with the use of “CalWin 300” Software as illustrated above.
(This software can be obtained by contacting customer service at Ideal Industries, Inc.)
Do not perform this step if software is already loaded
The software consists of two files titled “Setup.exe” and “Data001”. After you execute the setup.exe program in
the Windows (95 or 98) environment, you will have CalWin300 option in the PROGRAM set.
Execute “CalWin300” and you should get the screen shown in first Figure 3.
Description of CalWin300 window shown in Figure 4.
1. Main Display: Displays the main reading of the Meter.
2. Connection Indicator: “Connection” shows that the meter is connected to your
Computer and the meter and computer are communicating.
“Disconnection” shows that the meter and computer are not
connected or aren’t communicating.
3. Communication Port: Selects port available to connect to meter.
Selectable ports are COM 1 or COM 2.
4. Calibration Function Indicator and Selector:
Select item to be calibrated and select the Calibration Function desert.
5. Fine Frequency Selector:
Selects the Frequency that’s connected the meter, to select 50Hz or 60Hz.
Note:
Before the Calibration Function is selected, the function selected on the Meter has to be
confirmed, to prevent functional error from occurring.
