EZ-Check™ Switch
Source Mode: Slide the switch to select from Hi and low range pre-
set values and the mid ranger (Dial) is selectable. Dial the mid range
value and it will store the value with-in 5 seconds automatically.
Read Mode: Slide the switch to recall minimum and maximum
readings. Press the EZ-Dial™ Knob to clear the stored values.
Adjust the output up and down with the EZ-DialÔ knob. The increment is 0.01 mA (or 0.1 % if display units are % of 4-20 mA.)
Press while turning to adjust 10X faster – 0.10 mA (or 1.00 %.)
The Quick Reference Bar Graph indicates the input and output level to the PIECAL 134 in % of 4-20 mA with 1.0% resolution. If the
input or output signal is outside the normal operating range of the PIECAL 134 the Quick Reference Bar Graph in source mode will
flash, in Read mode display over range when above 24.5mA.
Bar Graph will flash when any error conditions exist.
Remove the back of the case and remove the jumper that is located in position J6 on the PC board. By doing so it places a 250Ω
resister in series with the output of the PIECAL 134. This internal resister eliminates the need to add an external load resister when
communicating with a HART® transmitter. This reduces the typical drive capability to 950Ω.

SOURCE/OFF/READ Switch
Slide the SOURCE/OFF/READ Switch to SOURCE to
output a mA signal and to do 2 - wire transmitter
simulation. Use the READ position to read mA signal and
power & measure 2 – wire transmitter.

EZ-Dial™ Knob
Turn the knob to change display in 0.01mA increments.
Push and turn for faster dialing. Push without turning to
clear EZ-Check™ HI/LO points in READ mode.
Press twice to select options:
In Source mode select –

HART® Protocol
An internal jumper enables the Power & Measure 2 – wire
transmitter mode to be compatible with HART®
communicators and transmitters.

Summary of Contents for PIE PIECAL 134

  • Page 1 Quick Reference 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. If the input or output signal is outside the normal operating range of the PIECAL 134 the Quick Reference Bar Graph in source mode will flash, in Read mode display over range when above 24.5mA.
  • Page 2 0 t o 6 0 V D C The PIECAL 134 can simulate a 2-wire transmitter in the 4-20 mA or % process loop. In source mode press the EZ-Dial™ Knob twice to get into the feature options. Then press the EZ-Dial™ Knob to select mA 2 – wire. The EZ-Check switch and EZ-Dial knob allow rapid and fine control of loop current.
  • Page 3 0 t o 6 0 V D C The PIECAL 134 supplies 15Volts or 24 Volts to the transmitter and displays the output in mA or % on the PIECAL 134 display. In read mode press the EZ-Dial™ Knob twice to get into the feature options. Then press the EZ-Dial™ Knob to select mA PWR - M. Then turn EZ-Dial™...
