1) Press
to select DC voltage measurement function, and automatically enter DC
voltage measurement function every time when the machine is started.
Description: Major display value refers to measured voltage value, and auxiliary displayed value
refers to the ratio between current measurement value and full measurement range.
2) Connect test lines as indicated in chapter “1.4 Measurement wiring”.
3) Select measurement range as required, and may select automatic measurement, or press the
softkeys of Measurement range+ (
) and Measurement range- (
) to select fixed
measurement range, which have same effect as keys of
and
.
4) Press the softkey of Relative (
) to record the current value, after which display the
difference between actual measurement value and current recorded value.
5) Press the softkey of Display (
) to switch modes, and refer to the chapter of
User
interface
for details.
6) If necessary, press
to configure the following measurement parameters: integral time,
input impedance and zero calibration method, and refer to the chapter of
Measurement
configuration
for details.
7) If necessary, press
to configure math operation function (limits, dBm, dB and relative),
and refer to description in the chapter of
Math operation
for details.
2.1.2 DC voltage ratio measurement
Basic Information
Ratio measurement refers to that measure input voltages to main input terminal and sense
terminal with multimeter, and work out the ratio.
Voltage ratio= Voltage value of main input terminal/Voltage value of sense terminal.
Main input LO terminal and sense LO terminal have to share common reference points, and
their voltage difference can not exceed ±2V.
Ration measurement is automatic measurement range measurement, and automatic zero
calibration is started. Main input terminal can measure up to 1000V voltage at most, and
sense terminal to 12V voltage at most.
