Troubleshoot Loop Problems
Quickly diagnose ground fault and current leakage with the patented loop diagnostic technology (US Patent# 7,248,058).
Calibrate I/P, P/I & other Pressure Instruments
Compact design for easy carrying & connection directly to hand pump or process. Use a cable for long term pressure tests on the bench or with future wireless pressure modules.
Calibrate Milliamp & Voltage Receivers
Calibrate recorders, digital indicators, stroke valves or any instruments that get their input from a 4 to 20 mA loop or voltage devices. Easily set any value quickly to within 0.001 mA or 0.001 V with the adjustable digital potentiometer “DIAL” or use preset LO 4.000 mA (0.00%) and HI 20.000 mA (100.00%) EZ-CHECK™ settings. Store any three mA or V output values for instant recall.
Calibrate quickly with automatic output stepping
Press & hold the dial to automatically step from 4 to 20 in 2, 3 or 5 steps or choose a continuous ramp.
Calibrate using Loop Power
Check loop wiring and receivers by using the PIE 901 in place of a 2 Wire transmitter with any loop power from 3 to 60 V DC.
Measure Milliamp Control Signals
Check controller outputs or measure the milliamp signal anywhere in the loop. Measure 0.000 to 24.000 mA (-25.00 to 125.00%) signals with greater accuracy than a typical multimeter.
Calibrate 2 Wire Transmitters with Built-In power supply
The PIE 901 can simultaneously output 24V DC to power any and all devices in a process loop using the internal batteries and internal switching power supply, while measuring the output of a 2 Wire Transmitter and any other loop devices. Powers HART™ transmitters with built-in 250 ohm resistor simplifying hookups with HART communicators.
