Inner Load Calibration
1. Make sure that DG1000Z has been warmed up for at least 30 minutes. Connect
the channel output terminal of DG1000Z (take CH1 as an example, the
calibration method is also applicable to CH2) and the voltage input terminals of
the digital mutlimeter using a BNC-Dual banana plug connecting wire, as shown
in Figure 2-3.
2. Press Output1 corresponding to CH1 on the front panel of DG1000Z to turn on
the channel output.
3. Turn on the digital multimeter, select the ACV measurement function and set the
range to “Auto”.
4. Enter the DG1000Z calibration interface and press Cal Item to select Inner
Load.
5. Press Cal Point and the cursor switches to the first calibration point in the ID
column.
6. You need to calibrate each calibration point twice (otherwise, you cannot select
the next calibration point).
a) Calibration without 50Ω load:
Press Meas Val and the MeasValue column of the point selected becomes
editable. At this point, use the numeric keyboard or the knob and direction
keys to input the current measurement value of the digital multimeter. Press
Input Val to write the measurement value into the system. At this point,
“Please connect 50 ohm load.” is displayed on the instrument screen and
the cursor switches to the ID column. Please connect a 50Ω load between
DG1000Z and the digital multimeter, as shown in the figure below.
