CHAUVIN ARNOUX CA-F403 [21/42] Programming of the adapter function scale factor

3.4.5 Programming of the Adapter function scale factor

To program the Adapter function scale factor :

1. From the OFF position, hold the key down while turning the switch

to until the "full screen" display ends and a beep is emitted, to enter

configuration mode. The display unit indicates the stored scale factor

value.

The default stored value is 1. The possible values are, in order: 1, 10k,

100k, 100m, 10m, 1m, 100, 10. (see §3.13

)

2. To change the value of the scale factor, press the key. The currently

active scale factor is displayed. Each press of the key displays the

next value in the list above.

Once the scale factor displayed has been chosen, turn the switch to another

position. The value chosen is stored (a double beep is emitted).

3.4.6 Default configuration

To reset the clamp to its default parameters (factory configuration):

In the OFF position, hold the key down while turning the switch to

until the "full screen" display ends and a beep is emitted, to enter the

configuration mode. The "rSt" symbol is displayed.

After 2 s, the clamp emits a double beep, then all of the digital symbols of

the screen are displayed until the key is released. The default

parameters are then restored:

Continuity detection threshold =40Ω

True Inrush triggering threshold =10%

Temperature measurement unit =°C

Adapter function scale factor = 1

3.5 VOLTAGE MEASUREMENT (V)

To measure a voltage, proceed as follows :

1. Set the switch to ;

2. Connect the black lead to the COM terminal and the red lead to "+".

3. Place the test probes or the crocodile clips on the terminals of the circuit

to be measured. The device selects AC or DC automatically according to

which measured value is larger. The AC or DC symbol lights in blinking

mode.

To select AC or DC manually, press the yellow key to reach the desired choice. The

symbol corresponding to the choice made then lights in fixed mode.
