3.4 Examples of programming
3.4.1 Operating in measurement mode
Gas settings:
 Gas 1: R134a, unit g/a
 Gas 2: disabled
 Gas 3: disabled
 Gas 4: He, unit mbar*l/s
RS-232 Interface settings:
 RS-232 protocol: ASCII
 Baud rate & End sign: 19200 / CR (must be identical with settings of PC))
 Control location: Local and RS-232 (if RS-232 is not enabled, control through the
interface is impossible)
With these commands the status of the Ecotec E3000, the status of the trigger and the leak
rates can be monitored in measurement mode.
Table 13: Commands and responses measurement mode
Command sent to

Ecotec E3000
Response received from

Ecotec E3000
Meaning
..........
*status? (CR) Requests the status of the Ecotec E3000.
MEAS (CR) Ecotec E3000 is in measurement mode.
*status:trigger? (CR) Requests the status of the trigger for all enabled gases.
OFF (CR)

ON (CR)
Both leak rates are below trigger value.

One or both leak rates exceed the trigger value.
*read 1? (CR) Requests the leak rate for gas number 1 (R134a).
3.9 g/a (CR) Leak rate Gas 1 (R134a)
*read 4? (CR) Requests the leak rate for gas number 4 (He).
2.5E-5 mbar*l/s (CR) Leak rate Gas 4 (He)
..................
If an error occurs, the status changes from MEAS to ERROR, the error number can be queried and no leak rates will be
available anymore. If the problem has been fixed the error can be acknowledged and the unit will start up again and go
back into measurement mode.
*status? (CR) Requests the status of the Ecotec E3000.
ERROR (CR) Ecotec E3000 currently shows an error.
*status:error? (CR) Requests the error number the Ecotec E3000 currently shows.
ERROR 47 (CR) Error number 47 (Transpector over pressure!)
*read 1? (CR) Requests the leak rate for gas number 1 (R134a).
E08 (CR) ERR_NO_DATA, no data available as unit currently shows an error.
…..
*cls (CR) Acknowledges (clears) the error message.
OK (CR) Ecotec E3000 has received request okay, unit will start up again.
*status? (CR) Requests the status of the Ecotec E3000.
ACCL (CR) Ecotec E3000 is starting up.
