Adjustment Procedure
You can use this procedure to adjust the HFP1000 probe to meet the warranted specifications. This
procedure should only be performed if the probe fails to meet the Performance verification tests for
Output Zero.
Gain which affects LF attenuation accuracy cannot be adjusted during routine calibration. Probes
which fail LF attenuation accuracy during performance verification must be returned to the factory
for rework.
To assure probe accuracy, check the calibration of the HFP1000 every 1000 hours or once a year if
used infrequently. Before calibration, thoroughly clean and inspect the probe as outlined in the Care
and Maintenance section.
To assure the probe will meet the published specifications over the entire temperature range,
adjustment must be performed in a controlled ambient environment with temperature of 23 °C ±5
°C.
CAUTION: The adjustment procedure will require removal of the probe control circuitry
cover. This cover is part of the ESD protection system of the HFP1000. To protect the
probe, you should perform the entire procedure on a static dissipating work surface. Wear
an antistatic wrist strap and follow standard static control procedures.
Test Equipment Required
Table 3 List of Required Equipment lists the test equipment and accessories (or their equivalents)
that are required for complete calibration of the HFP1000 Probe. Specifications given for the test
equipment are the minimum necessary for accurate calibration. All test equipment is assumed to be
correctly calibrated and operating within the specification listed. Detailed operating instructions for
the test equipment are not given in this procedure. Refer to the test equipment manual if more
information is needed
If alternate test equipment is substituted, control settings or calibration equipment setups may
need to be altered.
