Palmer Wahl P32 | Process Signal Pocket Calibrator | mA and V, 150 ppm
The Palmer Wahl P32 is a handheld process signal calibrator for commissioning and maintaining sensors and transmitters that use signals such as 4-20 mA or 0-10 V. It measures and generates current and voltage with 150 ppm (0.015%) of reading accuracy, measuring up to 50 V and simulating up to 15 V. Ramps, steps and scaling are programmable, and a 250 ohm resistor allows HART transmitters to be checked without disturbing digital communication.
Key features
- Measure and source mA and V, resolution down to 1 µA and 1 mV
- Low temperature coefficients: 15 ppm/°C (V), 20 ppm/°C (mA)
- 24 V loop supply, active or passive loops
- Simple or cyclic ramps with 1 to 3,600 s start delay
- IP54 housing, quick connect terminals and backlit graphic display
- USB port; five interface languages
Supplied with protective boot, four AA batteries, wrist strap, two measurement leads and carrying case. A rechargeable battery pack and charger are optional, and NIST calibration is available.
