Troubleshooting - VOLTCRAFT VC276 TRMS Bedienungsanleitung

13. Troubleshooting

The multimeter was designed using the latest technology and is safe to use. However, problems and malfunc-
tions may still occur.
This section explains how to troubleshoot common issues:
Always observe the safety information in these instructions.
Error
The multimeter does not
work.
The measured value does
not change.
The multimeter cannot take
measurements in the 10 A
range.
The multimeter cannot take
measurements in the mA/
µA range.
Erratic measurement dis-
play in the mA/µA range.
Repairs other than those described above should be performed only by an authorised specialist. If
you have questions about the multimeter, please contact our technical support team.
Possible cause
Is the battery flat?
Have you selected the wrong meas-
urement mode (AC/DC)?
Did you use the wrong measurement
sockets?
Is the hold function enabled?
Is the fuse in the 10 A input defective?
The PTC fuse was triggered, which
limits the measurement current.
The internal resistance of the
integrated PTC fuse increases slowly
during a long measurement.
Possible solution
Check the status. Replace the batteries.
Check the display (AC/DC) and select
another mode if necessary.
Compare the connection with the
display.
Disable the hold function.
Check the F1 fuse.
Reduce the measuring current or switch
to the 10 A measuring range.
Limit the measurement time. A pause
in the measurement allows the fuse to
cool down.
