(4) When in Voltage calibration page, press “
ENTER
” to confirm.
(5) First do the low voltage range calibration (16V), the instrument will set the output
voltage to 1.00V and the cursor is stopped at position [1] as Figure 3-77 shows. Enter the
voltage measured by DVM (4 digits after decimal point) and press “
ENTER
” to confirm.
(6) Press “
” again to do the low voltage range calibration for its second point, the
instrument will set the output voltage to 15.00V and the cursor is stopped at position [2]
as Figure 3-77 shows. Enter the voltage measured by DVM (4 digits after decimal point)
and press “
ENTER
” to confirm.
