PIE 434 mA High Accuracy 4-20mA Process Loop Calibrator
Easy to use - The PIECAL 434 you can check, calibrate and measure all your current signal instruments in a 4 to 20 milliamp DC loop. It can be used at any access point in your loop. Source & Read 0.000 to 24.000 mA, Simulate a 2 Wire Transmitter or use the PIECAL 434 to simultaneously power your 2 Wire Transmitter and measure its output.
- Easy to read - Turn on backlight & easily see the display in dark areas of the plant.
- Troubleshoot loop problems - Quickly diagnose ground fault and current leakage with the patented loop diagnostic technology (US Patent# 7,248,058).
- 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 PIECAL 434 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 PIECAL 434 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 PIECAL 434 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.
- Read DC volts - The PIECAL 434 can measure from -60.00 to +60.00 VDC with 0.01 Volt resolution. Use it to check loop power supplies, I/V converters, 1 to 5 Volt signals, and other voltages making it unnecessary to carry a multimeter.
- Evolutionary design - PIECAL Calibrators are designed and built by members of the same team that designed and built the calibrators manufactured by Fluke* under the Altek* label. The PIECAL 422 mproves upon other brands by including a rubber boot, tilt stand, backlit display with larger digits, rugged switches and a battery compartment for fast battery changes.
