Memory / Rs 232; Rs 232 Characteristics - Chauvin Arnoux C.A 6549 Manual De Instrucciones

§
Once the step function is defined, set the
switch to Adl. Step and select Step Function n°3
using the 4 key.
§
Start the measurement by pressing START/
STOP
§
During the measurement, the following screens can be accessed by pressing the DISPLAY key.
§
At the end of the measurement, the following are indicated :
-the difference ∆R in insulation resistance between
the final resistance (with the highest test voltage)
and the initial resistance (with the lowest test
voltage)
- the difference ∆V between the final and initial test
voltages.
- the slope of the curve in ppm / V
- the capacitance
§
Pressing the GRAPH key displays the
resistance versus applied test voltage curve.
Using the4,3, key, it is possible to scroll the
various samples recorded and, for each recable, to
know :
- the insulation resistance value
- the applied test voltage
- the time of recableing.
6.1 RS 232 CARACTERISTICS
q
The baud rate can be adjusted to 300, 600, 1200, 2400, 4800, 9600, or "Parallel" for printing on parallel
printers via the optional serial / parallel adapter.
This adjustment is performed in the SET-UP (see § 4.5)
q
Data format : 8 data bits, 1 stop bit, no parity, Xon / Xoff protocol
