CAUTION. The adjustment procedure requires removal of the
instrument covers. These covers are part of the ESD protection system
of the AP015. To protect the instrument, the entire procedure should
be performed on a static dissipating work surface only. The technician
should wear an antistatic grounding wrist strap and follow standard
static control procedures.
Test Equipment Required
The adjustment procedure requires a subset of the equipment required for
Performance Verification. Refer to Table 1 located in the Performance
Verification procedure.
If alternate test equipment is substituted, control settings or calibration
equipment setups may need to be altered. Alternate models of test equipment
may have different connector styles requiring adapters not included in the
equipment list.
Preliminary Procedure
1. Remove the two screws that secure the plastic cover on the cable end of
the ProBus interface housing. Gently pull on the probe cable to slide the
circuit board assembly from the metal housing.
2. Connect the AP015 (without the compensation box cover ) to the
oscilloscope using the setup for the DC Accuracy check in the
Performance Verification Procedure. (Refer to Figure 1 in the
Performance Verification section).
CAUTION. The compensation box cover serves to align the
ProBus connector pins during mating. With the cover
removed, care must be used to assure correct alignment of
the connector pins. Applying power with the pin alignment
incorrect may damage the probe.
3. Turn on the oscilloscope power switch to allow the probe to warm up at
least 20 minutes before proceeding with the gain adjustment.
