Operating Controls and Components

Setup

If a problem is reported with an instrument, it is sometimes wise to investigate operation before the unit is
reset, but generally resetting the electronics is the recommended starting point in the process.

Instrument Reset/Self Tests

The batteries must be removed from the instrument to reset the internal microprocessor electronics. Follow
the battery removal instructions in the Maintenance section on page 11.
Because the instrument uses very little power, the reset will not occur immediately upon battery removal until
the capacitance of the circuit is discharged. To speed this discharge, after the batteries are out, press the
backlight or timer button for about 10 seconds. The electronics will now properly reset upon battery
installation.
Remove the probe from the probe storage channel and unplug the probe connector from the instrument by
pulling on the connector body. Do not pull on the cord.
