2) Connect test leads to the measured voltage as Figure 2-5, red test lead should be connected to
terminal HI, and the black one to terminal LO.

3) Select proper range according to input DC voltage.
Range
200mV, 2V, 20V, 200V, 1000V
Input protection

value
Note:
Except for 1000V, all ranges are allowed to exceed range by 20%.
In 1000V range, OL will show if input voltage exceeds 1050V.
1000V input protection is provided in arbitrary ranges.
4) DC input impedance setting (only for scales of 20V and below)
There are two options of input impedance: [Auto] and [10M]. For scales of 20V and below, [Auto] means
the input impedance is over 10GΩ, otherwise the input impedance is 10MΩ.
5) Relative value setting
Turn the relative operation on, the displayed value is actual measured value minus the set relative value.
About relative value setting, please refer to 2.10 Mathematical Functions.
6) Reading speed
Press [Speed] to select proper reading speed during measurement.
7) History data review
User can check the history data by number, bar chart, trend chart, and histogram.
Note:
when the input terminal is in dangling state (no voltage input), random reading between ±20V will
