scription is as below.
Pins
4

Before connecting the hardware device that controls the analog in-
terface, make sure that the hardware device does not output a volt-
age higher than 20% of the specified value to the pin, otherwise the
instrument will be damaged. For example, when setting the voltage
or current, the input voltage can't exceed 12V, otherwise the instru-
ment will be damaged.
In analog quantity remote control mode, the analog quantity input
pins should be used in combination, and cannot be partially con-
nected and partially left floating.
Safe electrical isolation is set between this analog interface and in-
put electrode. Do not connect any ground wire of the analog inter-
face to the positive and negative terminals of the input interface.
