3.10 Adapter Function (Adp.)

This function is used to connect any adapter ensuring the
conversion of a physical quantity (mechanical, electrical, etc...)
into a DC or AC current ≤ 4 V.
This function also has a programmable scale factor by
decade from 0.001 to 100,000 capable of direct reading (with
possible display of the multiple: "m" for "milli" and "k" for
"kilo"), for the adapters having a transfer ratio equal to a
whole multiple of 10.

The table below shows the different sensitivities of a direct-
reading adapter after selection of a scale factor.
Sensitivity S (mV/A)
(example in Amperes)
10 mV/kA (0.01 mV/A)
100 mV/kA (0.1 mV/A)
1 mV/A
10 mV/A
100 mV/A
1000 mV/A (1 mV/mA)
10 mV/mA
100 mV/mA
The example given in Amperes (A) is valid for any other
quantity: humidity (% HR), light (lux), speed (m/s), etc...
Scale factor programming
I I I I I
1. Maintain the yellow key pressed and select the "Adp."
position on the rotary switch: the display indicates the
programmed scale factor (1 by default) as follows:
Display 1 m 10 m 100 m 1
2. To change the scale factor, press the yellow key
successively until the required value is obtained.
3. Use the rotary switch to memorise this value.
Implementation
I
1. Connect the adapter to the clamp
2. Program the scale factor if necessary (see § above)
3. Set the rotary switch to position "Adp".
4. Select the type of voltage using the yellow key if
necessary (AC or DC)
