ITech IT-M3900D Series User Manual

Basic Operation
Ch1 Set the parameters of channel 1 (programmed
channel).
Mx Indicates the slope factor of channel 1.
Mb Indicates the offset of channel 1.
Ch2 Set the parameters of channel 2 (upper limit
channel).
Mx Indicates the slope factor of channel 2.
Mb Indicates the offset of channel 2.
Ch3 Set the parameters of channel 3 (lower limit
channel).
For the IT-M3900D series of unipolar
power supplies, the voltage/current lower
limit does not need to be specified. There-
fore, the Ch3 parameters here do not
need to be set.
Mx Indicates the slope factor of channel 3.
Mb Indicates the offset of channel 3.
Analog Conversion Relationship Introduction
When the analog quantity control function of this series of instrument is used,
the user needs to set the conversion relationship of the analog quantity ex-
pected value based on requirements. The analog quantity values in each chan-
nel all follow the calculation relationship of y=Mx+b. The user needs to set the
MX (slope coefficient) and MB (offset) values in different channels in the analog
quantity menu. For calculation of the analog quantity value. The user can calcu-
late the M and b values based on the analog requirements in accordance with
the formula below.
Taking the Ch1 programming channel as an example, the user needs to convert
the values of Mx and Mb according to the following formulas, and then set the
two values through the front panel keys or SCPI remote commands.
The principle of parameter setting of Ch1 and Ch2 and Ch3 is the same, so
the description will not be repeated.
