UNI-T UT60F, Руководство по эксплуатации, Страница: 18 / 42

Note
l
In each range, the Meter has an input impedance of
10M
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).
l
When DC voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove testing leads
from the input terminals.
B. AC Voltage Measurement
(see figure 4)
Warning
To avoid harms to you or damages to the Meter from
eletric shock, please do not attempt to measure
voltages higher than 1000V rms, although readings
may be obtained.
The AC Voltage ranges are:
Model UT60F : 400mV,4V,40V,400V and 1000V;
Model UT60G : 600mV, 6V, 60V, 600V and 1000V.
To measure AC voltage, connect the Meter as follows:

1. Insert the red test lead into the HzV
Ω
terminal and
the black test lead into the COM terminal.
