3 Figure 2-5 shows the HI/LO outputs of the DC calibrator connected to the DC
reference input of the range calibrator. Ensure that the Guard and LO output of
the DC calibrator are floating, and are not connected to the earth ground.
4 Switch the power meter on.
5 Preset the instrument:
Press
then .
6 Set the display units to watts:
Press
, , .
7 Set the display resolution:
Press
,then press until is selected.
8 Set the range calibrator as follows:
– RANGE: 100 mW
– POLARITY: NORMAL
–FUNCTION: STANDBY
– REF SWITCH: EXT
–LINE: OFF
There is a small risk of mild electrical shock from the chassis of the 11683A
Option H01 range calibrator unless the power meter is connected.
When switching the range calibrator to STANDBY, allow enough time for the
range calibrator to settle to its zero value before attempting to zero the power
meter. This settling would appear on the power meter display as downward drift.
When the drift has reached minimum, (typically less than 60 seconds), the range
calibrator is settled.
