PD9501 Multi-Function Calibrator
SIGNAL MEASUREMENT
The calibrator can measure voltage, active current,
passive current, thermocouple signal, and RTD.
When measure function is not in use press [Measure]
to turn o the measure mode to conserve battery power.
Voltage, Active Current Measurement
① Connect the black wire to the common terminal,
connect the red wire to the measure terminal
② Press [Measure]to open measure function
③ Press [Signal]to toggle signal type
④Shows value in the LCD screen

Passive Current Measurement
①Wiring as the 2-wire or 3-wire system
② Press Blue [Signal]to set signal type to 24 V loop
③ Generator outputs 24 V (or 16 V when via DIP
switch to low power mode
④ Shows value in the LCD screen

To view or adjust cold junction temperature for
thermocouple:
① Press [Cold End] to display cold end temperature
② If the LCD displays “RJA” the cold end is collected
by the internal sensor and cannot be modied.
③ Select the “M” on the LCD to manually set the
cold end value.
PROGRAMMABLE OUTPUT
Scaled Output Function (n/m)
The voltage, current, and thermocouple signals can be
scaled by n/m.
Output value = (Main Set Value) × (n/m)
①Press to change the main setpoint
② Press [Program] to open split output mode to
display n/m menu
③ Set (m) from 1 to 20
④ Set (n) from 0 to 20
⑤ Press yellow [Output]to open/exit the output
⑥ Press [Program] to exit the split output function
Linear Output Function
The signal value can be output linearly according to the
time set by the user.
① Press to set value for the main set point
② Press [Waveform] to display “sweep”. This enables
linear output function.
③ Press [Program] to set output time for rise time,
hold time [top], fall time, hold time [low].
Press to set time between 0-999s.
④ Press [Program] again to set number of linear
outputs from 0-999.
⑤ Press yellow [Output]to open/exit the output
⑥ Press [Program] to exit the linear output function

RTD and Thermocouple Measurement
①Connect the black wire to the common terminal,
connect the red wire to the measuring terminal
② Press blue [Measure] to set signal type to
K/E/J/T/R/B/S/N/RTD/Ω
③ Value is displayed on the LCD screen
