B&K 8510 instruction manual Getting the calibration mode state（61H）, Calibrate voltage value（62H）

If Load is not in protection state, users could do the calibration operation.

37. Getting the calibration mode state（61H）

1st byte	Start bit ( AAH )
2nd byte	Address (0—0XFE)
3rd byte	Command（61H）
4th byte	Calibration protection state
From 5th to 25th byte	System
26th byte	Sum code

NOTE

Represent calibration protection state by one byte. Each byte is defined as:

From high to low

7 6 5 4

3 2 1 0

0 byte：protection state，0 represent not in the protection state ，1 represent in protection state.

38. Calibrate voltage value（62H）

1st byte	Start bit ( AAH )
2nd byte	Address (0—0XFE)
3rd byte	Command（62H）
4th byte	Voltage calibration point（1~4）
From 5th to 25th byte	System reserve
26th byte	Sum code

NOTE

Current calibration standard points have four: 1, 2, 3,4.

39. Sending the actual input voltage to calibration program（63H）

1st byte	Start bit ( AAH )
2nd byte	Address (0—0XFE)
3rd byte	Command（63H）
4th byte	The lowest byte of actual voltage
5th byte	The lower byte of actual voltage
6th byte	The higher byte of actual voltage.
7th byte	The highest byte of actual voltage.
From 8th to 25th byte	System reserve
26th byte	Sum code
