• Setup
General
Inputs to the unit are analogue current or voltage type. They are rated
for measuring category III signals with a voltage of 300 V
eff
to earth.
The input and output type are jumper selectable and their ranges are
set by the values used during calibration.
• Calibration
General
All instruments are calibrated before leaving the factory and should not
need adjustment unless a change of range is required or until the next
scheduled calibration.
Equipment requirements
• A suitable DC Power Supply
• A suitable DC mA or Voltage source
• An accurate digital multimeter (accurate to 0.0 mV and ±1 μA)
Procedure
1. Remove the instrument from the case and confirm that the jumpers
are in the correct positions for the input and output type required.
2. Connect up the instrument.
3. Press the UP and DOWN buttons together. The Status LED will turn
Red to indicate that the unit is in calibration mode.
4. Set the input source to the minimum value required, e.g., 4 mA for
4-20 mA inputs.
. Adjust the output value using the up and down keys until the
multimeter shows the output value required at minimum input, e.g., 4
mA for a 4-20 mA output.
6. When you are satisfied with the output, press the ENT button. The
middle LED will switch on to indicate that you are calibrating the
maximum input and corresponding output values.
