6. “APO” Button
Pressing “APO ” key to trigger on or off APO mode,
and then APO annunciator will appear or disappear on
the display. Power is automatically turn off, if no opera-
tion for a period of time, and “APO” annunciator is dis-
played at upper-left when APO function is enabled.
7. “MIN/MAX” Button
Press “MIN/MAX” once to begin recording MIN and
MAX. Press “MIN/MAX” to select MIN or MAX or
MAX-MIN or AVG Hold down for 2 seconds to exit
MIN/MAX function.
In the MIN/MAX record mode can not power off,
must leave MIN/MAX record mode then power off.
OFFSET ADJUSTMENT
The OFFSET control is set at the factory to allow for the
variations found in standard thermocouples. By adjusting
the OFFSET control, you can optimize measurement ac-
curacy for a particular thermocouple at a particular tem-
perature.
Adjusting for T1 or T2 Accurate Measure-
ments
1. Connect the thermocouple to the T1 or T2 input con-
nector and turn the thermometer on.
2. Place the thermocouple in a known, stable temperature
environment at or near the temperature you wish to
measure, and allow the readings to stabilize.
3. Slowly adjust the OFFSET control so that the thermom-
eter reading matches the temperature of the known en-
vironment. Leave sufficient time between adjustments
to allow for measurement lag.
4. The calibration of the thermometer-thermocouple com-
bination is now optimized for measurements near the
temperature measured in step 2.
Resetting the OFFSET Control
To return the OFFSET control to the factory setting
without having to recalibrate the thermometer, perform the
following procedure:
1. Connect a thermocouple that is in good working order to
the input that is to be adjusted.
2. Place the thermocouple in an ice-water bath and allow
the readings to stabilize.
3. Slowly adjust the OFFSET control until the thermome-
ter reads 0°C (32°F).
Probe Detector
The red LED will be on when no K-type thermocouple
probe is inserted into the TEMP input of the meter, and
will be off after K-type thermocouple probe is inserted.
If the red LED stays on when thermocouple probe is at-
tached, check the thermocouple probe which might be
damaged.
OPERATOR MAINTENANCE
WARNING
To avoid possible electrical shock, disconnect the
thermocouple connectors from the thermometer before
removing the cover.
Battery Replacement
1. Power is supplied by 9V (NEDA 1604, IEC 6F22).
2. The “
” appears on the LCD display when replace-
ment is needed.
3. Remove the battery from battery contacts.
4. When not use for long time remove battery.
5. Don’t keep in place with high Temp, or high humidity.
Cleaning
Periodically wipe the case with a damp cloth and deter-
gent, do not use abrasives or solvents.
