4. HOLD button: Press the HOLD button to select the
DATA HOLD mode. Press the HOLD button again
to cancel DATA HOLD mode. The thermometer will
resume taking measurements.
5. T1: Thermocouple Input Connector.
6. T2: Thermocouple Input Connector.
7. ºC / ºF button: The ºC / ºF button switches between
Celsius (ºC) and Fahrenheit (ºF).
8. T1-T2 button: Use the T1-T2 button to select
differential temperature measurement. The
thermometer will measure the temperature of T1 and
T2 and display the difference (T1 minus T2). To use
this feature, you must connect two thermocouples to
the thermometer.
9. T1/T2 button: The T1/T2 button can select
11
thermocouple T1 as the input or thermocouple T2 as
OUTPUT
the input.
10. OFFSET: The OFFSET CONTROL allows you to optimize
measurement accuracy for a particular thermocouple
at a particular temperature.
11. OUTPUT: OUTPUT from standard 3 pole 3.5mm socket
(Fig 1).

OPERATING INSTRUCTIONS
1. POWER
Pressing the ON/OFF button turns the thermometer ON or OFF.
2. CONNECTING THE THERMOCOUPLES
The thermometer is used with one or two thermocouples.
The thermocouples plug into the T1 and T2 input connectors.

SELECTING THE TEMPERATURE SCALE

Reading is displayed in either Celsius (ºC) or Fahrenheit (ºF). To change the temperature scale, press the ºC / ºF
button.

SINGLE-THERMOCOUPLE TEMPERATURE MEASUREMENT

The thermometer displays the temperature of the thermocouple that is connected to the
selected input. Press the T2 button to display the temperature of the thermocouple connected
to the T2 input. Press the T1 button to display the temperature of the thermocouple connected
11
to the T1- input. If the selected thermocouple is unplugged or open-circuited, the thermometer displays an error.
