Ach DC Current Measurement (DCI-Ach)
1. Connect a DUT to the Ach mA and COM A terminals on the front panel.
2. Press .
WARNING:
Do not measure a current source whose potential is more than 250 V.
This instrument may be damaged and accidents causing injury may occur.
The mA terminal is protected from any applied over-current by a fast-blow fuse.
For more information on how to replace the current protection fuse, refer to Chapter 8, “MAINTE-
NANCE.”
Figure 4-8 DC Current Measurement (DCI-Ach)
NOTE:
Applying current causes the temperature to rise in the input terminals and internal circuits, so
thermo-electromotive force is generated by the temperature rise.
While in other function measurements, especially high-sensitivity measurements, wait until the
temperature stabilizes after applying the current.
