Figure 3-4 DC fixed point calibration interface
Calibration interface includes:
Right of interface: Users can set calibration parameters here.
Left of interface: The DC voltage and current values listed based on user setting;
Left corner of the interface: The DC measurement result is showed in DC ln area. Users
press the second button to select the DC current measurement value (put in IdcL) or DC
voltage measurement value (put in Udc). The calibration error is showed in Err area.
3.5.1 DC Voltage and Current Calibration
Set DC voltage (-10~10V), DC current (0 ~20mA);
Put out calibration power.
3.5.2 DC Transmitter
Set DC voltage (-10~10V), DC current (0~20mA);
Select Idc or Udc in output channel;
Set rated value;
Connect DC signal output of transmitter with PM605A DC signal input. The DC
amplitude will be showed in DC ln area and percentage error will be showed in Err area.
