2. SAFETY PRECAUTIONS

WARNING:

1. This instrument is designed to
accept low level signals supplied by
standard Thermistors. Under NO
circumstances should the input
voltage exceed the specified 50V
RMS.

2. To prevent ignition of a hazardous
atmosphere, batteries must only be
changed in an area known to be
non-hazardous.

CAUTION:

1. Do not use or store this instrument in
microwave ovens or any abnormally
hot or cold areas.

2. Weak batteries should not be left in
the instrument. Dead batteries can
leak and cause damage to unit.

DANGER:

1. Voltages present at the Thermistor

may also be present at the battery
terminals. Always disconnect the
Thermistor when changing batteries.

16. CALIBRATION SCREEN

The thermometer is factory calibrated and
does not require calibration before use.
The Calibration function allows single point
calibration of the thermometer, at any
temperature point to compensate for
Thermistor off-set error. It is NOT
necessary to perform a field calibration to
obtain specified meter accuracy. Use the
field calibration feature to improve
thermometer/probe accuracy or to
compensate for Thermistor drift...

Before go into the calibration mode, must
enter the password. Press F2 to change to
the next digit. (Default Password is 9900)

- 19 -

There are two calibration options:

- adjusts at a single point. Offset

Offset
calibration can be performed at any
temperature in the offset range of ±5.00
°C or 9.00 °F
Slope – adjusts at two points. The two
calibration points must be at least 20.00
°C (36.00 °F) apart. The 2nd calibration
point should be at a higher value than the
1st calibration point.

Use the ▲ or ▼ keys to adjust the value to
match known temperature standard. Press
F1 to accept.

Do not clean with abrasives or solvents.
Use mild detergents, never immerse nor
use excessive fluid.

23. BATTERIES

If there is no display when the
thermometer is turned on, check condition
of the three AA batteries. Also check that
the battery terminals are clean and
batteries are properly installed. If
replacement is necessary, refer to the
