Operators Manual
The Product indicates a pass condition with a checkmark and fail condition with
an X. The power-up selftest is a go/no-go test. For example, if any of the tests
fail, a red x is shown on the Voltage, Frequency, or L-N-PE test lines.
If the Product detects that the power line is improperly connected, for example
the line or hot wire is reversed with the neutral wire, it shows Fail, In this case,
remove the power cord and correct the problem before trying to power the
Product on. The Product shows Pass for several seconds while it performs
additional internal circuitry tests, if all tests pass and the power line is properly
connected. A similar Fail indication is shown in the voltage and frequency tests if
the power supply voltage or frequency is out of specified limits.
The polarity of the neutral and the line wires must be correct for the
Product to power on. If the L-N-PE test fails during the power-on
process, the neutral and the line wires could be miswired at the
Mains connection socket. This probable wiring error must be
corrected. Only a qualified service technician should make this
change.
When the mains power tests finish, the Product initializes to Meter mode
operation.
During the power-up process, the display shows a message indicating that the
relays require cleaning.
The message indicates that relays for the Ground Bond Resistance function and
Loop/Line resistance function need to be cleaned with an internal cleaning
procedure. The message appears if more than 90 days has passed since the last
cleaning.
1. Push Setup>Maintenance>Relays cleaning procedure to clean the relays
2. Ignore the cleaning request with the EXIT softkey if necessary, or push the
When EXIT is selected the Product goes on to its reference state directly without
executing the relay cleaning procedure. However, the message is shown again
during the next power-up until the procedure is run.
During the power-up process, the Product, by default, measures the residual line
resistance in the mains supply.

at any time. The Product's Ground Bond Resistance and Loop/Line
resistance specifications are dependent upon how often you clean the relay.
See the 5322A Specifications online for details.
Continue softkey to start the process. When Continue is selected, the
Product prompts to remove all test leads from the front-panel terminals and
after confirmation it starts the relays cleaning. The Procedure takes about 2
minutes. Then the Product resets to its reference state of METER mode
operation.
