Chapter 5: General Troubleshooting

The following is a list of issues that may arise while using the Multimeter and

its solutions. Please use the corresponding steps when troubleshooting. If you

are still unable to resolve, please contact Teledyne Test Tools.

➢

If the screen of the Multimeter is still dark with nothing displayed
after pressing the power key:

1. Check if the power has been connected correctly.

2. Check if the main power switch on the back panel has been turned

on.

3. Check if the power fuse has blown. Replace it as desired if it has

blown.

4. Restart the Multimeter after all the above steps are complete.

5. If the instrument still cannot start up properly, please contact

Teledyne Test Tools.

➢

The reading does not change when connecting an AC current
signal:

1. Check if the test lead has been connected to the current jack and LO

jack correctly.

2. Check if the fuse in the current location on the back panel has

blown.

3. Check if the correct measurement connectors have been

selected (DCI or ACI).

4. Check if the input is ACI but the measuring location is DCI.
