Operating Instructions
Read RTD Sensors
Choose this function to measure temperatures with an RTD probe or sensor.
Move the power switch
w
to READ 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 for the
UNITS and RTD (Choose from one of Platinum 100Ω, or 1000Ω, Copper 10Ω or
50Ω, or Nickel 120Ω curves).
Note: Pt 100Ω
3850 is the most common RTD type.
Disconnect all wires from the sensor and connect the PIE 830PM to the inputs of
the device using 2, 3 or 4 wires. For 2 Wire RTDs connect the read 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). The PIE 830PM
automatically detects how many wires are connected using a patented circuit and
indicates each wire that is connected. Any wires that are not connected or broken
are indicated by the 830PM. This is useful for troubleshooting the sensor.
Signals above the maximum scale are limited by protection circuitry with “OVER
RANGE” on the display and the red OVERLOAD LED lit.
The 830PM measures the input signal and constantly updates the display with
the current reading. Move the EZ-CHECK switch
q
to MAX to see the highest
reading and to MIN to see the lowest reading. Press and hold the knob
e
to clear
the MAX and MIN readings.
