will retain the readings in memory. The meter must be cooled down or warmed up, as the case may be, before
normal operation can be resumed. If the meter has displayed OVER RANGE after displaying either TOO HOT or
TOO COLD, but has not shut down, this message indicates that the TemProbe sensor was being exposed to
temperature levels beyond the proper operating range. If TOO HOT/OVER RANGE has been displayed, but the
meter has not shut down, the TemProbe sensor may be short circuited.
TOO LOW
This message will appear as part of the NO LIGHT/BATTERY/TOO LOW sequence, when the battery charge is too
low to support use of the light.

This message is displayed when the meter has been placed in the TREND mode. TREND readings are not certified
for accuracy.
UNDER TEMP
This display advises the operator that the temperature measurement being attempted exceeds the lower range of
the meter
UNITS - XX
This message will be displayed to indicate the units in which readings are being stored. It is also one of the
parameters displayed after SHIFT/SHIFT is pressed.

This signal will be flashed when the VelGrid mode is selected, and also upon each subsequent operation of the
READ key.
