Measuring Resistances And Continuity (Ohmmeter) - Facom 714 Guía De Instrucciones

Beyond 1400A DC, the display indicates «-OL» or «+OL», according to the polarity
of the current measured.
Beyond 1400A peak (AC), the display indicates "OL".
Specific characteristics in MIN/MAX mode:
Extreme capture time: about 100 ms, displayed every 400 ms.
Specific characteristics in PEAK mode:
Intrinsic error: 10%L +5 pt.
Capture time for PEAK value: 1 to 4 ms according to peak value.
Measuring continuity
• Connect the measurement cords onto the tester's terminals.
• Set the rotating switch to the "continuité Ω" position.
• Connect the tester to the resistance to measure. Once contact is made (circuit closed), the
buzzer sounds constantly when the value of the resistance measured is below 40 Ω (value
programmable from 1 to 40 Ω).
This measurement is performed in the 400 Ω range only. There is no manual or automatic
range switch. Beyond 400 Ω, the display indicates OL.
There is no compensation for the measurement cords' resistance (low
resistance measurement).
To view the minimum and maximum values of the current reading, press the "MIN/MAX"
key several times.
Setting the continuity threshold: press and hold the yellow key, set the switch from OFF to
the Ω position. Then, change the value by pressing the yellow key several times.
Measuring resistance
• Connect the measurement cords onto the tester's terminals.
• Set the rotating switch to "Ω".
• Press the yellow key once to select the "Ω" function.
• Connect the tester to the resistance to measure.
Resistance measurements are performed over 4 ranges: 400 Ω, 4000 Ω, 40 k Ω, and
400 k Ω, although the buzzer is deactivated in the 400 _ range, unlike in continuity
measurement. The ranges are selected automatically by the tester. Beyond 400 k Ω, the
display indicates OL.
The resistance of the measurement cords is not compensated (low resistance measurement).
To view the minimum and maximum values for the current reading, press the "MIN/MAX" key.
