Ground continuity resistance measurement

Any measurement is performed by using the parameters stored in the active memory (see MEMx
indication in the LCD screen right hand side )
Connect the measurement leads on the specimen before starting the measurement by pressing on
the green MEASUREMENT push button.

In the following example, the thresholds are in ohm. Priority is given to the resistance measurement ,
the voltage drop is recalled in a small window in the right hand side LCD screen corner.
If the thresholds are set in volts, the R and U display windows are exchanged.

Fig 9.10

If the AUTO test time has been selected, every second the value of the RISE time counts down one
unit, then the value of the HOLD time and at least the value of the FALL time. When the FALL time
reaches 0 the output current is cut off automatically. According to the resistance value during the test
time in comparison with the H LIMIT and L LIMIT limits, the red LED (FAIL) or the green LED (PASS)
is illuminated.
At the end of the test, the unit cut off the current and END OF TEST appears at top of the screen.
