Fluke 787 Calibration
The Fluke 787 is a process calibrator, which is unusual to calibrate because it both sources and measures. Each direction has to be verified independently – an instrument can source 12.000 mA accurately while reading an applied 12.000 mA incorrectly, and only checking one direction hides that.
June Company calibrates the Fluke 787 for process instrument technicians, plant calibration teams, and field service engineers. Every point is measured against reference standards, with as-found readings recorded before any adjustment and as-left readings afterwards, so you can see what condition the instrument was actually in when it arrived.
What we verify on the Fluke 787
- Pressure measurement through each module used.
- 24V loop supply output.
- mA source and mA measure, verified separately in each direction.
- Voltage source and measure across ranges.
- Each RTD and thermocouple type supported.
- Frequency and resistance functions.
FAQs
What happens if it comes back out of tolerance? We record the as-found condition and tell you, because measurements you took with it since its last calibration may need reviewing. That is the reason as-found data matters.
Can it be adjusted if it has drifted? Where the instrument supports adjustment, yes – and the as-found and as-left readings are both recorded so the change is visible.
Calibration is documented and returned with the instrument. If we find a fault that calibration cannot correct, we quote the repair before going any further. Email us or submit a service request.
