Milwaukee Handheld TV SM806 User Manual

GENERAL OPERATION:  
TAKING pH MEASUREMENTS:  
The meter is supplied com-  
plete with a 9V battery.  
Remove the battery com-  
partment cover on the  
back of the meter and in-  
stall the battery while pay-  
ing attention to its polarity.  
Always remove the electrode protective  
cap before taking any measurement. If the  
electrode has been left dry, soak the tip  
(bottom 2.5 cm) in M10000 rinse solution  
for a few minutes to reactivate it.  
USER MANUAL  
Select the pH range with the  
“RANGE” key.  
Connect the MA851D/1  
probe to the meter.  
PORTABLE  
pH/EC/TDS/Temperature Meter  
Immerse the tip (2.5 cm) of  
the probe into the sample and  
stir gently.  
Read the pH value when the  
clock symbol stops blinking.  
Turn the instrument on by  
pressing the ON/OFF key.  
At start-up, the LCD  
shows the percentage of  
the remaining battery life  
for a few seconds, and  
then the current measure-  
ment.  
To select the temperature measurement unit  
(°C or °F), press and hold the “ON/OFF” key  
until “TEMP” and the current temperature unit  
are displayed on the secondary LCD. Use the  
“SET” button to select the unit and then press  
the “ON/OFF” key a couple of times to return  
to normal mode.  
To activate the HOLD  
function, keep pressed the  
“HOLD” key. The mea-  
sured value will be fro-  
zen on the display and  
the “HOLD” message ap-  
pears on the secondary  
LCD.

Combined Meter  
pH CALIBRATION PROCEDURE:  
A) Preparation:  
Buffer solutions:  
1. pH 7.01 / 6.86 (MA9007 / MA9006)  
2. pH 4.01 (MA9004) for acidic calibration  
(pH < 7) or pH 10.01 / 9.18 (MA9010 /  
MA9009) for alkaline range (pH > 7).  
Use two beakers for each buffer solution:  
one beaker for rinsing the probe, the other for  
calibration. In this way the cross contamina-  
tion between solutions is minimized.  
B) Procedure:  
Enter the pH mode with the “RANGE” key.  
Select the calibration buffer set: press and  
hold the “ON/OFF” key until the LCD shows  
“TEMP”. Press again this key and the  
“BUFF” message will appear; then select  
the desired buffer set with the “SET” key:  
“7.01 pH BUFF” (for standard solutions: pH  
4.01, 7.01, 10.01) or “6.86 pH BUFF” (for  
NIST solutions: pH 4.01, 6.86, 9.18). Press  
the “ON/OFF” key again to exit.  
To set the measurement range (pH, µS, ppm),  
press the “RANGE” key. The chosen mode  
will be stored until next change.  
Before taking any measurement, make sure  
that the meter has been calibrated (the “CAL”  
tag is displayed on the left lower corner of the  
LCD).  
After measurements, switch the meter off by  
pressing the “ON/OFF” key. The “OFF” mes-  
sage appears on the LCD; release the button.  
Store the electrode with a few drops of stor-  
age solution in the protective cap.  
Remove the protective cap, then immerse  
the probe in the first buffer solution.  
Press and hold the “ON/OFF”  
key until “CAL” is displayed  
on the lower LCD. Release  
the button and the message  
“7.01 pH USE” (or “6.86 pH  
USE” for NIST buffer set) will  
be displayed.  
For a single point pH calibration, place the  
probe in any buffer from the selected set  
(e.g. pH 4.01 or 7.01/6.86 or 10.01/9.18).  
The meter will automatically recognize the  
buffer value, store the calibration point and  
return to normal mode.
