Temperature Offset Adjustment; Continuity Testing - Martindale Electric ET5 Instruction Manual

3.21 Temperature Offset Adjustment

The offset adjustment allows an individual Type K thermocouple
to be optimised for the best measurement accuracy at a chosen
reference temperature.
The adjustment is accessed by removing the battery cover (see 4.1).
Connect the thermocouple to the input socket and place the
thermocouple in a known, stable temperature environment at the
reference temperature and allow the readings to stabilize.
Slowly adjust the TEMP OFFSET until the electrical tester reading
matches the temperature of the known environment.
Leave sufficient time between adjustments to allow for measurement
lag.
The calibration of the thermometer-thermocouple combination is now
optimized for measurements at the reference temperature.

3.22 Continuity Testing

COM
Connect the black test lead to the terminal and the red test lead
+
to the terminal.
Set the rotary switch to the position.
Press the SEL button once to select the continuity function. The LCD
will display .
Taking all necessary safety precautions connect the test leads to the
circuit being tested.
If the resistance is <30Ω, the buzzer will sound continuously and the
green LED will illuminate. The resistance value will be displayed if
<500Ω.
