9) Verify channels
that are closed
(optional).
ROUT:MULT:CLOS? Press SHIFT > press CARD > select VIEW > select
SLOT1: 7751 or 7753. Press EXIT when finished.
10) Perform
measurement.
READ? Take reading from display.
11) Perform cable

all channels.
ROUT:OPEN:ALL Press OPEN > select ALL.
Test step notes:
1. Resetting the 2790 opens all channels, selects the DCV function (auto range), and selects the I-source of the 7751/7753 module.
For remote programming, *RST places the 2790 in the one-shot trigger mode. For front panel operation, FACT defaults places the
2790 in the continuous trigger mode.
2. This step sets the V-source to output 500V, which is a typical voltage for this test. Note that this menu is also used to set the
I-source output. Simply skip over the I-source setting.
3. This step selects the high resistance calculation (R = V
SOUR
/ I
MEAS
). Selecting S1VOHMS sets the DMM to DCV, 10V range.
4. This step closes the channels to make the test connections for the HIPOT test. It assumes the single stage inflator is connected as
shown in Figure 5-3.
5. This step is optional. Use it to verify that the correct channels are closed for the test.
6. For remote programming, READ? triggers and requests a single reading.
7. Performs cable discharge for input channels 1 and 2, and opens all channels.
8. This step closes the channels to make the test connections for the second HIPOT test. It assumes the dual stage inflator is
connected as shown in Figure 5-5.
9. This step is optional. Use it to verify that the correct channels are closed for the test.
10. For remote programming, READ? triggers and requests a single reading.
11. Performs cable discharge for input channels 4 and 5, and opens all channels.
