B&K 1786B, 1788, 1785B Configuration, Voltage calibration, Current calibration, Finish calibrating

5.1 Configuration

Start the PC1785B_1788 System, the windows is as follows:

Voltage calibration

Current calibration

The diagram of connecting the multi- meter to the calibrated power supply

The diagram of connecting the multi-

meter to the calibrated power supply

Before the calibration, please click “Config” button to set the COM interface, address and baud rate. The default Com port is COM, and the default baud rate is 9600. Please make sure that the baud rate and address in the software and in power supply are the same.

5.2 Voltage calibration

Step 1: Prepare to use multi-meter to measure the output voltage, and connect the voltage meter to the power supply according to the diagram in the above windows.

Step 2: Click “Linked” button. It will go into Calibration mode, the Rmt and Cal indicators will light up.

Step 3: Fill the first voltage value you measured from the multi-meter to the blank of “0.000V”, and click “OK” button to confirm the value.

Step 4: Fill the second voltage value you measured from the multi-meter to the blank of “0.000V”, and click “OK” button to confirm the value.

Step 5: Fill the third voltage value you measured from the multi-meter to the blank of “0.000V”, and click “OK” button to confirm the value.

5.3 Current calibration

Step 1: Prepare to use multi-meter to measure the short circuit current, and connect the current meter to the power supply according to the diagram in the above windows.

Step 2: Click “Linked” button, it will go into Calibration mode, the Rmt and Cal indicators will light up.

Step 3: Fill the first current value you measured from the multi-meter to the blank of “0.000A”, and click “OK” button to confirm the value.

Step 4: Fill the second current value you measured from the multi-meter to the blank of “0.000A”, and click “OK” button to confirm the value.
