ROUBLESHOOTING
If a problem occurs on start-up or during normal operation, refer to the problems described
below. If a problem persists after following the steps below, contact Bonitron Tech
Support, the product supplier or your system integrator for assistance.
Repairs or modifications to this equipment are to be performed by Bonitron approved
personnel only. Any repair or modification to this equipment by personnel not approved
by Bonitron will void any warranty remaining on this unit.

high
Table 5-1: Troubleshooting
• Ensure that the input power cable is connected firmly to the unit
and to a functioning power source at the correct voltage.
• Make sure the input circuit breaker/switch has not tripped.
• Ensure that the commanded current is sufficiently high to
appreciably increase the voltage in a timely manner.
• Check the connections between the unit and the load, making
sure that the connection is solid, that the polarity is correct, and
that nothing is shorting out the terminals.
• Run the system with the load disconnected and verify it reaches
the commanded voltage. If not, or if the terminal voltage as
measured with a separate voltage meter does not match the
displayed voltage, the internal circuitry may need service.
Consult Bonitron for service options.
• Check the output connections to make sure there is good contact
to the load.
• Make sure there is voltage at the output terminals first checking
the display, then verifying with a voltage meter.
• Run the system with the load disconnected and the output
terminals shorted together to verify it produces the commanded
current. If not, the internal circuitry may need service. Consult
Bonitron for service options.
• Remove any obstructions blocking the vent
• Ensure that the fan turns on when the system is activated, and
that the air drawn into the fan is less than 40°C
• If the system continues to overheat, the internal circuitry may
need service. Consult Bonitron for service options.
• Check the connections between the unit and the load, making
sure that the connection is solid, that the polarity is correct, and
nothing is shorting the capacitor being tested.
• Large capacitors and capacitors with high ESRs may take a long
time to charge and discharge, possibly exceeding the 30 minute
limit imposed on each portion of the test cycle.
• Excessively leaky loads may not allow the charging current to
drop below the 1A requirement to move to the "Hold" phase of a
test cycle. Check for parasitic loads.
• Ensure that the test cable's clip leads are firmly connected to the
test capacitor terminals as close as possible to the capacitor itself.
