Wahl 2500M, 1370M, 2500MVX, 2500MX, 1370MX Quick Start Manual

Initial Checkout

These simple steps will verify the correct operation of your Heat-Prober:

1) With no probe plugged in, switch the Function Switch to the Normal Monitor
(N) position.

2) After the display stabilizes, you will see

This indicates an “open line” at the probe interface.

3) Plug your probe into the Heat-Prober.

4) The Display will indicate the temperature of the probe. In most
circumstances, this will be room temperature.

5) If you have a TCMR model Heat-Prober, the switch on the front of the meter
will change the display from Fahrenheit to Centigrade.

Additional Checks

If you wish to verify the Peak Hold function, use the following procedures:

6) Switch the Function Switch to the Peak Hold (P) position.

7) Heat the probe.

8) When the reading stabilizes, note the indicated temperature.

9) Cool the probe.

10) Note that the indicated temperature does not change as the probe cools.

11) Switch the Function Switch to the Normal Monitor (N)

position to read the true temperature of the probe.

If the unit does not behave as expected, the first thing to check is the power.

1) If your model comes with an external charger, plug it in and recheck the
unit. Allow battery to charge before using.

2) If your model has a 9 volt battery, remove the battery compartment securing
screw, open the compartment, and remove the battery.

3) Check the voltage (9 volts, nominally) and replace if necessary.

4) Reinstall the battery, close the compartment, and recheck the Heat-Prober
for proper operation.
