Table 5.2 DC Voltage Measurement Parameter Setting
Parameter Description
Range* Auto, 100 mV, 1 V, 10V, 100 V, 1000V
Impedance
Available to set when the Range is a specified value rather than
Auto.
10 GΩ, 11.2 MΩ
- When you select "11.2 MΩ", the input impedance for all the
ranges is 11.2 MΩ.
- When you select "10 GΩ", the input impedance for 100 mV
and 1 V ranges is "10 GΩ", but the input impedance for the
10V, 100 V, 1000V ranges is "11.2 MΩ".
Rate Fast, Medium, Slow
NOTE
- 20% over range on all ranges except 1000 V range.
- The range can be set to Auto or a specified value (available range options for Range
menu).
- A 1000 V input protection is available in all ranges and a 20% overrange is available on
all ranges except 1000 V.
- If the reading exceeds 1000 V in 1000 V range, "OVER LOAD" will be displayed.
4. Click or tap to enable or disable the relative operation function. When
enabled, the displayed reading value is the result obtained by subtracting the set
relative value from the actual measurement value. For the relative value setting
methods, refer to descriptions in "
Math Operation
".
5. Read the measured value
When reading the measurement results, you can use the arrow keys to switch the
reading rate.
6. Hold the reading data
Press
to run and hold the reading data displayed on the screen.
5.3.2 To Measure DC Current
The instrument can measure up to 10 A(DM858)/3 A(DM858E) DC current. The
following section introduces the connection methods and measurement methods of
DC Current.
