Resistance Measurement; Diodes Test - LIMIT 500 Auto Manual De Instrucciones

3. Set the rotary switch to an appropriate measurement position A
...
range for DC or A~ for AC. When the value is unknown
always start from the max range 10 A.
4. Break the current path to be tested. Connect the red test lead to
the more positive side of the break and the black test lead to the
more negative side of the break.
5. Turn on power to the circuit. 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.

Resistance measurement

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
Ω range.
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, or the circuit is open.
• The test leads can add 0.1Ω to 0.3Ω of error to resistance measure-
ment. To obtain precision readings in low-resistance measurement,
that is the range of 200Ω, short-circuit the input terminals before-
hand and record the reading obtained. This is the additional
resistance from the test lead.
Diode test
Use the diode test to check diodes, transistors, and other semicon-
ductor devices. The diode test sends a current through the semicon-
ductor junction, and then measures the voltage drop across the
junction.
