What to Check When There Is a Problem
If the CA0 does not work properly even after you check the items below or you have a
problem that is not listed below, contact Omega Engineering.
Symptom
Even when the power is on,
nothing appears on the LCD.
Current output is not working.
The output or measured values
are strange.
Control through the USB interface
is not working.
"Err60" appears when the power
is turned on.
"Err61" or "Err62" appears when
the power is turned on.
Items to Check
• Are the batteries inserted properly?
• Have the batteries worn out?
• Have the fuses melted (blow out)?
SOURCE mode:
• When the current is output, is the load
resistance too high?
(Open output terminals or leads)
SIMULATE mode:
• Is the input voltage too low?
(Check the external DCV power supply.)
• Is it possible that the values are being affected by
noise?
• Are the communication settings correct?
• The settings that were specified with the setup
function are incorrect.
Refer to section 4.6, "Setup Function," to return
the CA450 to its factory default settings.
• The calibration data is incorrect.
Refer to section 4.7, "Additional Power-on
Functions," to return the calibration data to its
factory defaults.
If after you perform the above operations, errors
still appear every time you turn on the power,
repairs are necessary.
