1. Rotate the selector knob to v (VAC). Remove the ohms connection and connect the
5700A to the Ë and â inputs on the GMM.
2. Step 24: Apply 1000.0V, 1 kHz. Allow for settling; then press t [Proceed].
3. Step 25: Apply 100.00V, 1 kHz. Allow for settling; then press t [Proceed].
4. Step 26: Apply 290.00V, 1 kHz. Allow for settling; then press t [Proceed].
5. Step 27: Apply 29.000V, 1 kHz. Allow for settling; then press t [Proceed].
6. Step 28: Apply 2.9000V, 1 kHz. Allow for settling; then press t [Proceed].
7. Step 29: Apply 290.00 mV, 1 kHz. Allow for settling; then press t [Proceed].
8. Step 30: Apply 29.00 mV, 1 kHz. Allow for settling; then press t [Proceed].
9. Set the 5700A to Standby.
AC mA µ µ µ µ A Calibration
1. Rotate the selector knob to i (mAµA).
2. Remove the ac connection and connect the 5700A to the a and â inputs
on the GMM.
3. Step 31: Apply 290.00 mA, 1 kHz. Allow for settling; then press t [Proceed].
4. Step 32: Apply 29.000 mA, 1 kHz. Allow for settling; then press t [Proceed].
5. Step 33: Apply 2.900 mA, 1 kHz. Allow for settling; then press t [Proceed].
6. Step 34: Apply 290.00 µA, 1 kHz. Allow for settling; then press t [Proceed].
7. Step 35: Apply 29.00 µA, 1 kHz. Allow for settling; then press t [Proceed].

AC Amps Calibration
