Reading The Measurement Memory - Chauvin Arnoux C.A 43 FILEDMETER Mode D'emploi

The second group contains the state of the function in 3 characters :
- LO AL and HI AL OFF
- BAT
- SEN
- COMM
The sensor code is a digit between 0 and 255 inclusive. It defines the linearisation curves to
use to obtain the display in the selected measurement unit.
A value comprised between 251 and 255 indicates that no probe is connected.
A value comprised between 250 and 139 indicates that a V/m measurement probe is
connected.
A value comprised between 138 and 0 indicates that a measurement probe in A/m is
connected.
Each V/m and A/m sub-assembly is divided into subgroups of 13 measurement points to
define the different linearisations. This latter information is only useful for decoding rapid
measurements.
READ THE MEASUREMENT MEMORY
For this read instruction to take effect, the instrument must be in read memory mode,
otherwise the instrument sends back the code Error 2 (ER2).
Codes to send to obtain the output of the contents of the measurement memory :
- 21 Hexa, 33 decimal
The response to this read instruction will be the output of the complete contents of the
measurement memory, in the form of 1920 lines maximum. The contents of the memory is
given from Dt to Dt if the recordings have been done in MIN/MAX record mode, or from
measurement to measurement, if they have been done in Measurement mode.
The information transmitted is given in accordance with the same format as for the
measurement printout in local mode. The output starts with the last memory cell containing
a measurement and ends with the first value memorised at address 000.
if the alarm is not On
ON if the alarm is On
- - - if the alarm is not in service
Digit corresponding to the remaining service life of the battery in %.
It is the same digit which appears when the instrument is
switched On.
Code of the probe in service.
Measurement unit in service or MR if the Read Memory mode
is selected.
