Status: 789 / 787B / 773 Current Production — original 787 Discontinued. We repair and calibrate all of them.
Common Fluke ProcessMeter Problems We Fix
- mA source or measure out of tolerance / drifting
- Blown input after voltage applied to the mA terminals
- No reading / won’t source or simulate mA
- Rotary function switch worn or intermittent
- Dead or faded display / missing segments
- Won’t power on / battery compartment corrosion
- 773: clamp jaw misaligned / non-contact mA reading off
- 789: 24V loop supply not working or out of regulation

Frequently Asked Questions
How much does Fluke ProcessMeter repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the unit, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most 787B, 789, and 773 repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
My ProcessMeter’s mA source or measure is out of tolerance — can you fix it?
Yes. mA source/measure drift is the most common ProcessMeter fault. We correct the cause and verify the mA, voltage, and resistance functions against our reference standards.
I applied voltage to the mA jacks and now it won’t read — is that fixable?
Yes. Input protection damage from voltage applied to the mA terminals is one of the most common 787/789 repairs. We restore the input circuitry and verify accuracy across all functions.
My Fluke 773 clamp reads mA wrong — can you fix it?
Yes. Clamp-jaw alignment problems that throw off the non-contact 4–20 mA measurement are a common 773 repair, restored and recalibrated so it reads accurately again.
My 789’s 24V loop supply stopped working — can you repair it?
Yes. Loop-supply regulation faults that stop the 789 powering a loop are a routine repair, restored so you can source and power transmitters in the field again.
What if my exact model isn’t listed?
We service every Fluke ProcessMeter configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses Fluke ProcessMeters?
Process instrumentation technicians, industrial maintenance, oil and gas field operations, pharmaceutical process control, water treatment, and HVAC technicians rely on the 787B, 789, and 773 for combined meter and loop calibrator work.
