11.4 READ THE MEMORY PROGRAM
This function is accessible in all operating modes.
Codes to send to the instrument to obtain the contente of the memory program:
- 2A Hexa, 42 decimal Corresponding graphic: *
The response to this message will be the emission by the instrument, to the TxD output, of the codes
corresponding to the values contained in the memory. The output format is the same as for the interrogation
of the memory when the instrument is switched On.
The non-programmed functions are indicated by three hyphens (- - -).
During the printout of the values contained in the memory program, the operation of the rotary switch, or
pressing one of the buttons, has no effect on the data output. Only the OFF position stops the instrument.
11.5 RAPID READ OF THE MEASUREMENT
This read instruction gives access to the measurement with a very short time constant. This allows
processing by peripheral computer.
To be taken into account, this read instruction must be sent to the instrument when it is in Measurement
or Record mode, otherwise an error code is sent back:
- Code Error 1 if the instrument is in Read Memory mode
- Code Error 3 if the instrument is in Programming mode
The minimum time between 2 read instructions may not be < 100 ms.
Two measurement values are available: normal measurement and PEAK measurement, the latter allowing
the analysis of pulse signals.
Reading the Normal 20ms measurement gives the measurement corresponding to the averaging of 80
measurements of 250µs.
This 20ms measurement is obtained by sending the following code to RxT :
- 22 Hexa, 34 decimal Corresponding graphic: «
Reading the PEAK measurement is obtained by sending a different code according to the type of PEAK
desired:
- to obtain the PEAK MAX 250µs value (measures 250µs max made during a 20ms measurement), you
must send the code:
- 23 Hexa, 35 decimal Corresponding graphic: #
- to obtain the PEAK MIN 250µs value (minimum value during a 20ms measurement), you must send
the code:
- 24 Hexa, 36 decimal Corresponding graphic: $
The output format is in binary on 2 bytes + trame byte (code ASCII 4)
See in appendix the coding of the response transmitted.
