Recording Data
Record the following data in a permanent log similar to the example
HI-2790B Operational Log on page 33.
4.2.1 Each log should identify the HI-2790B Power/Control Module serial
number and the serial numbers of the HI-1710 LCR and
HI-2623 Probe/Preamp Assembly.
4.2.2 Date.
4.2.3 Power/Control Module FWD, REF, DIFF, and RF Power readings
(at 1.0 mW/cm 2 ).
4.2.4 HI-1710 LCR bias voltage.
4.2.5 HI-1710 LCR ellipticity values (maximum, minimum, and mean).
4.2.6 Ambient temperature and Power/Control Module internal
temperature.
4.2.7 The REMARKS column, in addition to noting unusual
observations, should identify whether daily checks or 30-day
checks are being performed, the type of instrument being checked,
and so on.
4.2.8 Power/Control Module RF Power (at mW/cm 2 ).
4.2.9 The person performing the test should be identified in the Initial
