. The internal measurement of 0 V is adjusted.
The 5V internal measurement adjustment screen appears.
8.
Press
Done (F5)
. The internal measurement of 5V is adjusted.
The DC voltage adjustment screen shown in step 2 appears.

Press
ESC
. The screen shown in step 1 appears.
Adjusting the DC Current
2.
After step 1, use the ▲ or ▼ key to select
Current Source
, and press ENTER.
The DC current source adjustment screen appears. The CA700 generates 0 mA.
3.
Like the adjustment of the DC voltage, adjust the source value and the internal measurement.
The adjustment points are 0 mA and 20 mA. The source adjustment ranges are –0.2000 mA to
0.2000 mA and 18.0000 mA to 22.0000 mA.
Adjusting the Current Simulation
2.
After step 1, use the ▲ or ▼ key to select
Current Simulate
, and press ENTER.
The current simulation adjustment screen appears. The CA700 generates 1 mA.
3.
Like the adjustment of the DC voltage, adjust the source value and the internal measurement.
The adjustment levels are 1 mA and 20 mA. The source adjustment ranges are 0.9000 mA to
1.1000 mA and 18.0000 mA to 22.0000 mA.
Finishing the Adjustment
After finishing all adjustments, press ESC several times. The top menu that normally appears when
you turn the CA700 on appears.

Calibrating Internal Measurements
The CA700 has feature that measures the voltage and current that it is generating and displays the
source value as “- - - - - -” when the difference between the specified value and the actual source value
is greater than a given value.
You must adjust the source function as well as the internal measurement function. Adjust the
measurement using the source values after adjustment. In the case of voltage, the source values
would be 0.00000 V and 5.0000 V.
