Precision Digital PD675 4½ Digit Loop-Powered Meters

4½ Digit Loop-Powered Meters

The only tools needed for calibration are a calibrated current source, a flat head screwdriver & a Phillips head screwdriver. Please note that the meter must be disassembled in order to perform the setup functions.

Calibration Controls - Calibration of these meters is a two-step process involving four controls. These controls are located on the Display Board. The LO controls are on the right and the HI controls on the left. The pre-configured jumper array JP2 and JP3 are also located on the Display Board.

Calibration Procedure - Connect the 4-20 mA input signal. Apply 4 mA to the input and adjust the coarse and fine LO controls for the desired reading. Next apply a signal between 16 and 20 mA and adjust the coarse and fine HI controls for the desired reading. Complete the calibration by making any minor adjustments to the LO and HI displays.
