WARNING
HIGH VOLTAGE is used or exposed during the performance
personnel fail to observe safety precautions. REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
a. Turn on the TI and verify that it cycles through the self-check procedure. The
self-check ends with PASS, followed by the TI model number, 1012, and then REVA.
b. Connect the temperature probe (4101-10X) to one of the RTD input channels of
the TI. Verify that the TI is still in the resistance measurement mode; if not, press the
c.
Prepare an
ice bath to
determine the
probe resistance at
ice-point temperature,
zero degrees Celsius.
d. Place end of probe into the bath and allow at least 30 minutes settling time before
reading the resistance. This value should be approximately 100Ω as indicated by the TI.
Record this measurement for later use.
17. Ice Point Calibration of Temperature Probe
a. Performance Check
(1) Place configuration panel over front panel keyboard of the TI. Press SHIFT
and ENTER keys.
(2) The TI Units window displays PRB? Press YES to configure the probe.
(3) The Units window will prompt PRB#. Enter the probe or channel number
being used and press ENTER key.
(4) The TI should indicate OHM?. Press NO key until STD appears in the Units
window and then press YES.
(5) Several options are available under the STD function. Press NO key until
3850PT is displayed. Select this option by pressing YES key.
(6) The TI prompts Ro. Press ENTER key to continue.
