B. AC Voltage Measurement
(see figure 4)
(figure 4)
mean square value converter needs a longer time to stabilize.
To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure voltages
higher than 1000VDC / 750VAC rms although readings
may be obtained.
Warning
The AC voltage ranges are: 4.000V, 40.00V, 400.0V and
750.0V. To measure AC Voltage, connect the Meter as follows:
1. Insert the red test lead into the
terminal and the black
test lead into the COM terminal.
2. Set the rotary switch to and press BLUE button to select
AC measurement.
3. Connect the test leads across with the object being measured.
The measured value shows on the display.
Note
l
In each range, the Meter has an input impedance of 10M .
This loading effect can cause measurement errors in high
impedance circuits. If the circuit impedance is less than or
equal to 10k
, the error is negligible (0.1% or less).
l
When AC voltage measurement has been completed,
disconnect the connection between the testing leads and the
circuit under test, and remove the testing leads away from the
input terminals of the Meter.
l
True root mean square value stability period (Model UT60E):
When the reading obtained is less than 100 digits, the true root
When there is no input voltage, the maximum reading
displayed is 10 digits.
