OPERATION
DC Voltage Measurement
Warning:
To avoid personal injury, or damage to the meter from electric shock, please
do not attempt to measure voltages higher than 1000V although readings may be
obtained.
To measure DC voltage, connect the meter as follows:
•
Insert the red test lead into the V terminal and the black test lead into the COM
terminal.
•
Set the rotary switch to
.
•
Connect the test leads across with the object being measured. The measured DC
voltage’s true RMS value shows on the display.
•
When measurement has been completed, disconnect the connection between the
test leads and the circuit under test.
Note:
In each range, the meter has an input impedance of 10M
Ω
except 600mV range
has 3000M
Ω
. This loading effect can cause measurement errors in high impedance
circuits. If the circuit impedance is less than or equal to 10k
Ω
, the error is negligible
(0.1% or less).
Symbol
Meaning
LOW
Indicates lowest setup limit
AUTO
The meter is set to auto range with range for best resolution selected
SEND
Data output in progress
Backlight feature is on
HOLD
Data hold mode is active
PEAK HOLD Peak hold mode is active
Diode test
%
Frequency signal duty cycle. 4~20mA loop current as % reading
>OL
Input value overload for the selected range
Analogue Bar Provides an analogue bar graph of the present input, quick response
Analogue Bar Graph
The bar graph provides an analogue indication of the measured input. For most
measurement functions, the bar graph updates 10 times per second.
