With the 334 you can check, calibrate and measure all your current signal instruments in a 4 to 20 milliamp DC loop. The PIE 334 can be used at any access point in your loop. Source and read 0.00 to 24.00 mA, simulate a 2 wire transmitter or use the meter to simultaneously power your 2 wire transmitter and measure its output. Calibrate in confidence: accurate to +/-0.025% of span at 4.00 & 20.00 EZ-CHECK outputs.
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 0.01 mA with the adjustable digital potentiometer DIAL or use the preset 4.00 mA (0.0%) and 20.00 mA (100%) EZ-CHECK settings.
With the 334 you can calibrate using loop power. Check loop wiring and receivers by using the 334 in place of a 2 wire transmitter. PIE 334 uses any loop power from 2 to 100 V DC.
Read loop power with the 334. Check controller outputs or measure the milliamp signal anywhere in the loop. The 334 measures 0.00 to 52.00 mA (-25.0 to 300.0%) signals with greater accuracy than a typical multimeter.
Power and measure 2 wire transmitters with the 334. You 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 with any other loop meters.
Read DC volts with the 334. You can measure from -99.99 to +99.99 VDC with 0.01 volt resolution. Use 334 to check loop power supplies, I/V converters, 1 to 5 volt signals and other voltages making it unnecessary to carry a multimeter.
