3.0 OPERATING INSTRUCTIONS
3.1

The following instructions are found on the metal label fixed to the BAT-12.

They are reprinted here in case the label ever becomes defaced.

3.2

The special indications mentioned in 3.1 alert the user to unusual conditions

and can prevent the recording of erroneous readings.

3.3

When the instrument is switched on and a probe is connected, it should read

room temperature. This is normally about 25°C. Hold the tip of the probe between
the thumb and forefinger; if reading increases to 28-34°C, which is normal skin
temperature, it may be assumed that the instrument is working correctly. If the
instrument reads low, your hand may be cold. BAT-12 reads to 1/10°C.

3.4

Normal use of the thermometer is very simple. Switch ON, apply probe, read

temperature.

4.0 BATTERY REPLACEMENT
4.1

When a colon (:) appears in the center of the ditigal display, the battery needs

to be replaced. However, BAT-12 can be used without significant calibration error
for about one hour after the appearance of the colon.
