PIE 901 4-20mA Loop, voltage and Pressure Calibrator
Calibrate and measure all your current and voltage signal instruments in a 4 to 20 milliamp DC loop
• Compact, Accurate & Easy to use: Carry the small Model 901 to check, calibrate and measure all your current and voltage signal instruments in a 4 to 20 milliamp DC loop. It's easier to carry and use than other brands with confusing buttons, has laboratory accuracy plus advanced troubleshooting features! Optional rechargeable batteries for economical use or swap in a set of "AA" alkaline batteries to continue operating when away from the battery charger.
• Easy to read: Full color display with backlight - shines in dark areas of the plant.
• Troubleshoot loop problems: Quickly diagnose ground fault and current leakage with the patented loop diagnostic technology.
• Source milliamps: Calibrate recorders, digital indicators, stroke valves or any instruments that get their input from a 4 to 20 mA loop. Easily set any value quickly to within 0.001 mA with the adjustable digital potentiometer "DIAL" or use preset 4.000 mA (0.00%) and 20.000 mA (100.00%) EZ-CHECK settings.
• Automatic output stepping & ramping: 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 Model 901 in place of a 2 Wire transmitter. Uses any loop power from 2 to 60 V DC.
• Read loop current: Check controller outputs or measure the milliamp signal anywhere in the loop. The Model 901 measures 0.000 to 24.000 mA (-25.00 to 125.00%) signals with greater accuracy than a typical multimeter.
• Power & measure 2 wire transmitters: The Model 901 simultaneously outputs 24V DC to power any and all devices in a process loop using the internal batteries and internal switching power supply, while measuring the mA output of a 2 Wire Transmitter & any other loop devices. Powers HART transmitters with built-in 250 ohm resistor simplifying hookups with communicators.
• Source & Read DC volts: The Model 901 can generate 0.000 to 22.500 V DC and measures from -60.000 to +60.000 VDC with 0.001 Volt resolution. Great for calibrating 1 to 5 Volt inputs on recorders and PLCs. Use it to check loop power supplies, I/V converters and 1 to 5 Volt signals making it unnecessary to carry a multimeter to check process signals.
• Easily measure pressure with a plug in pressure module: Dual display of milliamp & pressure for easy calibration of I/P, P/I, gauges, or other pressure instruments with either loop power or using the 901's internal 24 volt supply. Choose from a wide selection of PIE pressure modules along with one of the hand pumps and tubing kits for a complete pressure calibration system. BlueTooth capable for wireless connection to pressure modules
