1. Insert the probe/preamp tube into the receptacle in
the HI-1710 front panel with the power OFF. The
preamp tube must be oriented with the locating
screw facing up. Be sure that the pins are securely
mated with the socket in the instrument front panel.
Note that the preamp tube is inserted into the probe
opening such that the indicator arrow on the brass
tube is aligned with the edge of the grounding ring.
2. Check that the input voltage select switch (located
on the rear panel of the unit) is set to the proper
voltage level. Connect theinstrumentto the AC
supply line.
3. Power is applied to the system by depressing the
power switch located in the upper right corner of
the instrument front panel. When the power is first
turned on, the microprocessor performs a series of
self-tests on the measuring circuitry of the meter.
Refer to section 6.0 (Test and Trouble Shooting) for
more information. When the initial tests are
complete, the system is in its default mode and
ready for operation.
4. Check the spacer cone for damage, discoloration, or
contamination. Accuracy will be affected by cone
wear or damage or by contamination by metallic
particles which may become imbedded in the cone.
Replace the cone if necessary. Replace the cone
only with a Holaday Industries replacement cone for
