Pocket-Mate mA Loop Calibrator

• Easy to use

With the PIECAL 134 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 134 to simultaneously power your 2 Wire
Transmitter and measure its output.

• 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.

• Monitor changes with bar graph

The Quick Reference Bar Graph indicates the input and output level
to the PIECAL 134 in % of 4-20 mA with 1.0% resolution. The Quick
Reference Bar Graph flashes when signals outside the normal
operating range is detected.

PIECAL 134

• Power saving output

Choose High Power 24V output to drive loops with up to 1200 Ohm
loads or extend battery life by selecting Low Power 15V output which
drives loops with up to 600 Ohm loads.

Actual Size

• Calibrate using loop power

Check loop wiring and receivers by using the PIECAL 134 in place of a 2 Wire transmitter. Uses any loop
power from 2 to 42 V DC.

• Read loop current

Check controller outputs or measure the milliamp signal anywhere in the loop. The PIECAL 134 measures 0.00
to 24.00 mA (-25.0 to 125.0%) signals with greater accuracy than a typical multimeter.

• Power & measure 2 wire transmitters

The PIECAL 134 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.

• 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 134 improves upon other brands by including a larger
display with larger digits and bar graph, rugged switches, belt clip 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.
