I have 4 Fluke 45's that were all damaged by either high voltage on the input or some sort of weird ground noise from testing a HV DC/DC converter. On a good Fluke 45, this measures 1K-Ohm dead nuts (in circuit). I took it apart because a good one measures 1K, but the diagram shows 3.3K.I've attached the schematic and the parts list. Offending part is R5.
I don't see "3.3K" anywhere in the parts list. I see R5 shown as 3.5KI also see that R5 and RT1 appear to have been hand-altered after the diagram was published.Perhaps you have the wrong schematic for your make/model/serial number.
What is the colour code of the resistor in the good Fluke 45?
Get a pair of new ones that will fit. This type of thing is not usually sold in pieces, not these cheapies at all.
This fuse like thing was in an Anritsu voltmeter. anyone know what it is ?
it's a rectifier, from an old stereo Gradiente DS 700, can't find the schematics either
