The START TIMER switch starts the dwell timer on the front panel to time test duration. The timer can
only be started when high voltage is energized. The timer is reset only after the high voltage is off and the
START TIMER pushbutton is depressed.
To set the H5CX timer.
1)
Press and hold ‘mode’ button for 3 seconds to enter program mode
2)
Set the time range using the ‘up/down’ push buttons (default 30min 00 sec)*
3)
Set the timer mode using the ‘up/down’ push buttons (default down)*
4)
Set the timer output mode using the ‘up/down’ push buttons (default F)*
5)
Set input signal width using the ‘up/down’ push buttons (default 20mS)*
6)
Set key protect level using the ‘up/down’ push buttons (UP-1)*
7)
Press and hold ‘mode’ button for 3 seconds to exit program mode
*press ‘mode’ button briefly after adjusting each parameter to move to next step

The METER MODE switch configures the current metering circuit for capacitance measuring or for
output current measurement.

The PUSH TO READ X1 pushbutton changes the scale of the CAPACITANCE metering. The modified
Wheatstone Bridge incorporated in this circuit indicates x10 readings without depressing the PUSH TO
READ X1 pushbutton. When in the x10 scale and the reading is below 6
µ
F, the PUSH TO READ X1
should be depressed to get an accurate load capacitance measurement.

This potentiometer is for zeroing the capacitance range at full scale prior to measuring the cable
capacitance.

These posts are for connecting the cable to the capacitance measuring circuit. The HOT post is for the
cable center conductor, the COM post is for the cable's grounded shield. Be sure the cable is de-
energized before connecting this low voltage circuit or damage will result. The resulting capacitance
measurement on the cable will identify the best operating frequency for that particular cable run. A
frequency table is provided in the section OPERATING THE EQUIPMENT.
