• Dead battery: The Fluke 78 requires a 9-volt battery to operate. If the battery is dead, the multimeter will not turn on. To fix this, simply replace the battery.
• No readings: If the multimeter is not displaying any readings, there could be a problem with the probes or the input jacks. To test the probes, connect them to a known voltage source. If the multimeter still does not display any readings, the input jacks may be dirty or damaged. To clean the input jacks, use a cotton swab and some rubbing alcohol. If the input jacks are damaged, they will need to be replaced.
• Erratic readings: If the multimeter is displaying erratic readings, there could be a problem with the internal circuitry. To test the internal circuitry, use a Fluke 78 service manual to troubleshoot the problem. If you are unable to fix the problem, the multimeter will need to be repaired or replaced.

Here are some additional tips for troubleshooting common Fluke 78 problems:

• Check the connections: Make sure that all of the connections are secure. Loose connections can cause inaccurate readings.
• Use the correct probes: Make sure that you are using the correct probes for the measurement you are trying to make. For example, do not use AC voltage probes to measure DC voltage.
• Calibrate the multimeter: If the multimeter is not calibrated, it may give inaccurate readings. To calibrate the multimeter, use the calibration procedures in the Fluke 78 service manual.
