9. Reading the calibration state
(28H)
Note:
1. We use 4 bytes to represent the maximum voltage value as follows:
Byte 3
Byte 2 Byte1
Byte
0
2. We use 1 byte to represent power supply’s state. Each bit is defined as
follows:
From higher bit to lower bit
7
6
5
4
3
2
1
0
0 bit
:
The output state, 0 is OFF, 1 is ON.
1 bit
:
Over heat protection, 0 is normal, 1 is abnormal.
2
?
3 bit: The output mode, 1 is CV mode, 2 is CC mode,3 is Unreg mode.
4
?
5
?
6 bit
:
The fan speed, 0 is stop, 5 is the maximum fan speed.
7 bit
:
Operation state, 0 is front panel operation mode, 1 is remote control
mode.
3. The frame format is the same as above
Note:
We use a byte to represent calibration protection state
,
each bit is defined as
follows:
from higher bit to lower bit
7

0 bit
:
Protection state, 0 is to disable protection, 1 is to enable the protection.
