INTRODUCTION
This instrument is a 3½ digit, compact-sized portable digital thermometer
designed to use external K/J/T/E/S type thermocouples as temperature
sensor.TemperatureindicationfollowsReferenceTemperature/VoltageTables
(N.I.S.T. Monograph 175 Revised to ITS-90) for K/J/T/E/S type thermo-
couples.
SAFETY INFORMATION
Itisrecommendedthatyoureadthesafetyandoperationinstructionsbefore
using the thermometer.
WARNING
To avoid electrical shock, do not use this instrument when working
voltages at the measurement surface over 24V AC or DC.
WARNING
To avoid damage or burns, do not make temperature
measurement in microwave ovens.
CAUTION
Repeated sharp flexing can break the thermocouple leads. To prolong
lead life, avoid sharp bends in the leads, especially near the connector.
The
symbol on the instrument indicates that the operator must refer to an
explanation in this manual.

CALIBRATION PROCEDURE
Note: The following calibration procedure should perform only by qualified technicians
who have access to the items as following.
Equipment: The class of calibrator had better 10 times greater than the measured meter.
1. Set the jumper position on J1 position.
2. Input DCV 25.6mV to the T1 after the display is stabilized (forward 4 digits), then
press “ ENTER “ key and "01" is displayed.
3. Input DCV 74mV after the display is stabilized, then press “ENTER “ key and "OL"
is displayed.
4. Input 0LC (K-type) after the display is stabilized, then press “ENTER “ key.
5. Don't push any key and the meter will turn off automatically after 10 seconds.
6. After adjustment set the jumper back to J3 position.
7. Turn on the meter then input 0LC (K-type). The display reading reads 0°C if
