11. Press the HOLD key to lock the T2 slope
calibration in, or press the CAL key to skip T2
slope calibration. In either case you will now
be in T1 = T2 offset calibration. To return to
normal operation press any key except CAL
key or HOLD
key.
If either T1 or T2 offset or slope were modified, CAL
1 or 2 will be lit.
12. The MATCH annunciator should be blinking.
When both readings (T1 and T2) are stable,
press the HOLD
key to lock the T1 = T2
offset calibration in. The MATCH annunciator
will remain lit.
13. This completes the two-point calibration.
14. To return to normal operation press any key
except ON/OFF key or the CAL key.
Matching T1 and T2 Procedure
This procedure requires both probes to be at the
same temperature.
1. Place both probes at the same temperature and
let stabilize.
2. Momentarily press the CAL key until the MATCH
annunciator is blinking. When both readings (T1
and T2) are stable, press the HOLD
key to
lock in the calibration.
Clearing an Individual Cal Point: Press CAL key
until the desired point is displayed, then press
CLEAR key.
Clearing all Cal Points: Press CLEAR key, then
CAL key. Unit reverts to factory calibration with no
offset or slope compensation.
