Operating Instructions
Source RTD
Choose this function to provide a simulated RTD signal into controllers,
temperature transmitters, indicators or any input devices that measure RTD

Move the power switch
w
to SOURCE then Double Click the EZ-DIAL knob to
get into the Double Click 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

10Ω or 50Ω, or Nickel 120Ω curves).
Note: Pt 100Ω
3850 is the most common
RTD type.
Disconnect all sensor wires from the devices to be calibrated and connect the
830PM to the inputs of the device using 2, 3 or 4 wires. For 2 Wire RTDs connect
the red lead into jack (1) and the black lead into jack (2). For 3 wire RTDs add a
black lead plugged into jack (3) and for 4 wire RTDs add a red lead plugged into
jack (4).
Instantly output your SPAN and ZERO output settings by moving the EZ-CHECK
