The load voltage indicated on the load module is below expected.
Ensure the load leads are as short as possible, twisted and use the
appropriate wire gauge. Ensure that voltage sense is used, this can
help alleviate the voltage drop across the load the leads.
The front panel keys are not working.
Check to make sure that the key lock has not been activated. LOCK
will be shown on the panel when the screen is locked. Press Shift +
Lock to unlock the keys.
The load won’t turn on.
If you are using the load key to try to turn the load on and the load
won’t turn on, it is possible that external control is activated and
that the LoadOn In setting is set to low. See page 143 for details.
The performance does not match the specification.
Make sure the device is powered On for at least 30 minutes, within
+20°C~+30°C. This is necessary to stabilize the unit to match the
specification.
