Backlit Display • Easy to use With the PIECAL 334 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 0.00 to 24.00 mA, Simulate a 2 Wire Transmitter or use the PIECAL 334 to simultaneously power your 2 Wire Transmitter and measure its output. Always on backlight & easily see the display in dark areas of the plant. • 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 preset 4.00 mA (0.0%) and 20.00 mA (100.0%) EZ-CHECK™ settings. • Calibrate using loop power Check loop wiring and receivers by using the PIECAL 334 in place of a 2 Wire transmitter. Uses any loop power from 2 to 100 V DC. • Read loop current Check controller outputs or measure the milliamp signal anywhere in the loop. The PIECAL 334 measures 0.00 to 52.00 mA (-25.0 to 300.0%) signals with greater accuracy than a typical multimeter. • Power & measure 2 wire transmitters The PIECAL 334 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. Actual Size The PIECAL 334 can measure from -99.99 to +99.99 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 334 improves 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. * PIECAL Calibrators are not manufactured or distributed by Fluke Corp or Altek Industries Inc, manufacturers of Altek Calibrators.
