[Test-Equipment] Parts for Fluke 87?

[jbarnes]

Hi group,

The yellow component is a a spark gap. It is there to protect the meter from over-voltage.

The manual for the 87 is available from www.fluke.com

Click 'SUPPORT' on the top menu

Click 'MANUALS' on the left menu.

Select 'discontinued products' under product category

scroll down the page and you will find the 87 service manual.

The manual contains the schematics.

Check the protection diodes and the 1k resistor.( page 5-14)


Regards,


John VE3XRY
