6. The value of compensated resistance of the cables which

will be subtracted from all subsequent continuity

measures is shown next to “Rcal” and the message

“Calibration OK” appears on the display.

7. To delete the value of compensated resistance, carry out a

new compensation procedure with a resistance higher than

5 such as, for example, with open leads. The value in Rcal

is zeroed on the display.

6.5.3. Measuring continuity

1. Position the cursor onto LOW by using the arrow keys

(,) and confirm with ENTER. The display shows the

screen to the side.

2. Press the ENTER key, activate “Settings” and possibly

change the desired parameters (see § 5.3.1). The

following parameters are shown on the display:

 RPE max  maximum threshold for continuity

measurement, which can be selected in a range 1 

5 in steps of 1

 Rcal  the value of resistance of the measuring

cables after calibrating them

 Rpe  the result of continuity measurement

 Itest  real test current

3. Press the ENTER key, activate “Cable calibration” (see § 6.5.2) to carry out the initial

calibration of the measuring cables.

Connect the instrument to the PV module/string being tested and to the main earth node of

the system as shown in
