Current Stock:

Product Description

Manufacturer: Mastech

Model: M9803R

Condition: Used. Comes in non-original packaging. This meter is in Good cosmetic condition except that the top has some big scuffs/stains. The photos show the exact item(s) the buyer will receive.

Notes: This meter is in Good working condition.  Readings the DC Volts, AC Volts, DC current, AC current, frequency, and 2-wire Ohms settings were close to the readings we would get on our reference meter.  Current readings are a little slow to stabilize after a change. The backlight works, and allows use in darkness (see photo #3).  No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
