Before Testing
• Unless specified within, use the default settings on the main unit during testing.
• The DL1740E and DL1740EL accept 4-channel input, so testing should be performed
on channels 1 through 4. However, the DL1720E has 2-channel input, so testing
should be performed on channels 1 and 2.
• Before testing, restart the unit while holding down the Reset key to initialize the
instrument.
• During testing, also hold down the Reset key when restarting.
2.2.1 Grounding Test
Product specification: 0.1
Ω
or less
Confirm that a current of 30 A flows between the FG inlet of the AC power supply input
and channel 4 of the BNC ground (or between FG and EXT. for the DL1720E), and that
the resistance value is 0.1
Ω
or less.
