Fluke 87 Fusible Resistor

On VDC range, the DMM reads zero volts with 9V input.

On Ohms range, with the input shorted, it should read near zero, but instead flashes &#039;OL&#039; rapidly.

120VAC mains input on the VAC range only reads a very low voltage.

Begin repair by disassembling. Take care not to break fragile plastic clips and tabs.

Locate the fusible resistor.

Testing the fusible resistor reveals that it is open-circuit. It should read near 1K ohms.

Replacement Vishay 1K metal-film 2W fusible resistor.

Install replacement resistor and re-solder.

Checking functionality with an 806-ohm precision resistor.

Checking DC voltage with a 5.000V reference.

120VAC mains voltage reads correctly.
