Source RTD
Choose this function to provide a simulated RTD signal into
controllers, temperature transmitters, indicators or any input
devices that measure RTD sensors.
Move the power switch
w
to SOURCE then Double Click the
EZ-DIAL knob to get into the Menu. Turn the knob to scroll
through the settings and press the knob to make your selection.
Select RTD for the FUNCTION, °F or °C for the UNITS and RTD
(Platinum 10, 50, 100, 200, 500 & 1000 Ohm (alpha = 3850),
Platinum 100 Ohm (alpha = 3902, 3916, 3926), Copper 10 & 50
Ohm, and Nickel 120 Ohm). Turn on SENSOR mA to check the
excitation current generated by the receiver.
Note: Platinum (Pt) 100Ω
3850 is the most common RTD type.
Disconnect all sensor wires from the devices to be calibrated and
connect the PIE 525Plus to the inputs of the device using 2, 3 or 4 wires.
Instantly output your SPAN and ZERO output settings by moving
the EZ-CHECK switch between HI and LO. You may also select any
third output setting (such as mid-range) using the SET position on
the EZ-CHECK switch. The output is adjusted in 0.1° increments
in LOW and 0.01° increments in HIGH resolution by turning the
knob
e
. Press and turn the knob for faster dialing with 10.0°
increments in LOW and 10.00° increments in HIGH resolution.
