a. Press the "Setup Menus" softkey.
b. Press the "Special Functns" softkey.
c. Press the "ACXfer Choice" softkey so that ON appears.
d. Press PREV MENU twice.
e. Set the 5700A to 1 V, 1 kHz, operate. Press the "Intrnl Xfers" softkey so
that OFF appears. (The "Intrnl Xfers" softkey appears only in the 5700A
ranges below 220 V and at frequencies below 120 kHz.)
f.
Press 0,V, 0, Hz, ENTER, on the 5700A. Leave the 5700A in standby.
3. The display prompts you for INPUT1 or 2. Verify that the [INPUT1] keycap
indicator is lit. Press the "Proceed With Cal" softkey. The display changes to:
Range
2.2V
LOCKED
4. Press the "DO Step" softkey. The display changes to:
Calibration: LF (10 Hz) Linearity
ENTER the exact value to do step.
Voltage= 2.000000
5. For all the AC cal points down to the 70 mV range, use the Fluke 792A AC/DC
Transfer Standard to adjust the AC voltage level being applied to the 5790A
INPUT1 connector. There are three procedures for AC calibration points,
depending on their amplitude. Go to the appropriate step as defined below:
Step 6: 2 V through 600 V
Step 7: 60 mV through 600 mV
Step 8: 2 mV through 20 mV
6. For an AC calibration point in the 2 V through 1000 V range, proceed as follows:
a. Obtain a copy of Figure 3-6, the worksheet for this group. Fill in the test
voltage and frequency and the associated 792A correction.
b. If the test voltage is above 220 V, add the 792A 1000 V range resistor to
the test setup as shown in Figure 3-8.
c. Press the "DO Step" softkey. This automatically selects the correct
5790A range.
d. Set the 792A INPUT RANGE knob to the appropriate position. Always
use the lowest range that will accept the input.
