4. In the Voltage calibration page, press “ ” to confirm.
5. The low voltage range calibration is done first. The instrument will set the output voltage
to 8.00V and the cursor stops at position [1] as shown in Figure 3-107. Enter the voltage
measured by the DVM and press “ ” to confirm.
6. Press “
” again to do the low voltage range calibration for the second point. The
instrument will set the output voltage to 115.00V and the cursor stops at position [2] as
shown in Figure 3-107. Enter the voltage measured by the DVM and press “ ” to
confirm.

7. Press “
” to do the high voltage range calibration. The instrument will set the
output voltage to 150.00V and the cursor stops at position [3] as shown in Figure 3-108.
Enter the voltage measured by the DVM and press “ ” to confirm.
8. Press “
” again to do the high voltage range calibration for the second point. The
instrument will set the output voltage to 525.00V and the cursor stops at position [4] as
shown in Figure 3-108. Enter the voltage measured by the DVM and press “ ” to
confirm.
