If the instrument appears to be not working properly, check all of the control settings and
connections. The following brief summary of typical problems for the user (along with the
most common solutions may help:
The Instrument is beeping
No output (and the Error LED does
not light).
Battery OK LED does not light when
pressing Test.
Battery OK LED does not light, but
Battery OK and Error signals of port
test positive.
Error LED on, even with no input
Error LED lights when Gate is turned
on
Error LED lights when Battery Test signal
is used
Excessive noise on the output

Problem Solving
Replace the 9V battery and reset the
alarm button on the rear panel
• One or both of the batteries are
uncharged (test batteries: recharge as
required.
• The Gate input is held low
(must be high for an output to occur).
• Power switch is not set to Off (set to Off).
• One or both of the batteries need
recharging.
• This indicates that the batteries are
almost fully discharged. The front panel
battery test requires a slightly greater
battery level to operate successfully.
• Low batteries (recharge).
• Excessive drive: Unit is limited to ±
100V in monopolar mode or ± 50V in
bipolar mode (reduce input drive or gain).
• Current mode: load is disconnected
(check wiring); or load impedance is too
high for limited output voltage capability
(cascade more than one unit).
• Battery charge is low (recharge)
• Gate signal erroneously connected to
Battery Test input (change connection).
• This is normal.
• Charger is still plugged in (unplug/
disconnect.
• In the lowest current range: stray
electrical interference can degrade noise
performance if it mostly couples into the
