4. OPERATION INSTRUCTIONS
WARNING
To avoid electrical shock or p
ersonal injury, do not apply
more than 20Vrms, between the thermocouples (s), or
between any thermocouple and earth ground.

If voltage on the measurement surfaces result in
potentials more than 1V between the two
thermocouples, then measurement errors may occur.
If the potential differences are anticipated between the
thermocouples, use electrically insulated thermocouples.
4-1 Temperature Measurement
Press " " key to turn on the thermometer.
Plug the thermocouple(s) into the thermocouple input(s)
as required. If no thermocouple is plugged into the
selected input or the thermocouple is "open circuit", the
appropriate display will show "- - - -.-".
Press "C/F/K" key to select the desired temperature scale.
Press "TYPE" key to select the thermocouple type
required.
Press "T1/T2/T1-T2" key to determine which of the T1, T2,
and T1-T2 readings appears in the main display or
secondary display.
To measure the temperature, touch the probe sensor on
the object whose temperature is to be measured.
Read the temperature on the display. The display shows
"OL" (overload) when the temperature being measured is
outside the valid measurement range of the meter.

4-2 MAX, MIN and AVG Function Operations
Press "MX/MN" key to enter to MX/MN mode and to step
through the maximum (MAX), minimum (MIN) or the true
average (AVG is a true 9.7 hours recording average)
mode. Auto power-off function will be automatically
disabled.
Press "T1/T2/T1-T2" key to toggle between present
reading of the T1, T2 and T1-T2 on the main display.
Press "MX/MN" key and the MAX, MIN and AVG reading
of T1/T2/T1-T2 will appear on the secondary display.

5. MAINTENANCE
5-1 Cleaning:
Periodically clean the case with a damp cloth and mild
detergent.
Do not use abrasives or solvents. Clean and dry as
required.
5-2 Battery Replacement:
When LCD display shows “ ”, the battery has had
insufficient power to support an accurate test. Replace
the batteries with Qty. 6 type AAA cells.
6. RECALIBRATION PROCEDURE
The thermometer should be calibrated once a year to
ensure its continued accuracy. Contact RS Components for
further details of calibration service. The address is given at
the end of these instructions.
