Calibrating High Temperature PINIP™ Probes
Special thickness standards are supplied with
F1 2 High Temperature PINIP™ Probes - see
page 44. These thickness standards should be
used in place of the calibration standard in Step 1
of "Calibration adjustment procedure" on page 27.
1. Place appropriate thickness standard over end
of PINIP™ probe.
2. Press CAL softkey.
3. Place probe on hot
reading.
4. Lift probe and then replace on hot surface to
take second reading.
5. Repeat as necessary until reading is stable.
6. Press SET to accept value.
