Voltage Dc And Ac - LIMIT 500 Auto Manual De Instrucciones

Voltage measurement DC and AC
1. Insert the red test lead into the VΩ terminal and the black test
lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in
V--range for DC or V~ for AC. When the value is unknown always
start from the max range 1000 V.
3. Connect the test leads across with the object being measured.
The measured value shows on the display.
Note
• Displays 1 selected range is overload; it is required to select a
higher range in order to obtain a correct reading.
• In each range, the Meter has an input impedance of approx.10 MΩ.
This loading effect can cause measurement errors in high im-
pedance circuits. If the circuit impedance is less than or equal to
10kΩ, the error is negligible (0.1% or less).
Current measurement DC
Warning
Never attempt an in-circuit current measurement where the voltage
between terminals and ground is greater than 250 V.
If the fuse burns out during measurement, the Meter may be damaged
or the operator himself may be hurt. Use proper terminals, function,
and range for the measurement.
When the testing leads are connect-ed to the current terminals, do
not parallel them across any circuit.
Measuring time for current should be less than 10 sec and interval
between measurement should be at least 15 minutes.
To measure current, connect as follows:
1. Turn off power to the circuit. Discharge all high-voltage capacitors.
2. Insert the red test lead into the A or mA terminal and the black
test lead into the COM terminal.
