● Current output calibration
(1) Select the [ Analog Output Calibration] tab.
(2) Select a desired channel to be calibrated.
Select [ch1] for control output 1 and [ch2] for control output 2.
(3) Select [Zero] from the zero span selection items.
(When selecting a channel, perform the [Zero] calibration first, and then
perform the [Span] calibration next since “Zero/Span” is set for one channel.)
(4) When clicking [Read] , the zero calibration current is output to the output
terminal of the channel you have selected.
For details about how to connect measuring instruments, refer to the
following Figures:
(5) Keep this status for approximately 30 sec.
(6) Read the current value in units of 0.001 mA from the ammeter, input it in
[Current (mA)/Voltage (V)] , and click [Write] .
(7) Select [Span] from the zero span selection items.
(8) When clicking [Read] , the span calibration current is output to the output
terminal of the channel you have selected.
(9) Keep this status for approximately 30 sec.
(10) Read the current value in units of 0.001 mA from the ammeter, input it in
[Current (mA)/Voltage (V)] , and click [Write] .
(11) If any channels to be calibrated remain, return to operation step (2).
