3.4.2 Performing an external calibration
Gas settings and interface settings as above.
With the following chain of command an external calibration of gas 1 (R134a) may be
controlled via RS-232. The progress of the calibration is shown on the main unit display,
any confirmations through the buttons of the main unit display nor the probe button is
impossible however.
*status? (CR) Requests the status of the Ecotec E3000.
MEAS (CR) Ecotec E3000 is in measurement mode.

*status? (CR) Requests the status of the Ecotec E3000.
MEAS (CR) Ecotec E3000 is in measurement mode.
*cal:start (CR) Starts calibration process.
OK (CR) Ecotec E3000 has received start signal.
*cal:status? (CR) Requests the status of the calibration.
T<20 MIN, CONFIRM (CR) If the Ecotec E3000 has been running for less than 20 min a warning
is sent by the Ecotec E3000 .
*cal:quit (CR) Acknowledges warning
OK (CR) Ecotec E3000 has received acknowledgement.
*cal:status? (CR) Requests the status of the calibration.
SELECT GAS (CR) Status is: gas to be calibrated must be selected.
*cal:select 1 (CR) Selects gas 1 (R134a) for external calibration.
OK (CR) Ecotec E3000 has received selection.
*cal:status? (CR) Requests the status of the calibration.
START CAL, CONFIRM (CR) Status is: ready for calibration.
If test leak rate setting and unit of test leak is known from last calibration process and identical, the calibration may be
started immediately (see next table), otherwise the test leak information has to be sent to the Ecotec E3000 first:
*cal:unit? (CR) Requests the set unit of the test leak rate.
g/a (CR) Unit of test leak rate is g/a.
*cal:leakrate? (CR) Requests the currently set leak rate for the external test leak.
10.4 (CR) Leak rate is 10.4 (g/a).
*cal:leakrate 4.1 (CR) Sets the leak rate of the external test leak used to 4.1 (g/a).
OK (CR) Ecotec E3000 has received new setting.
*cal:status? (CR) Requests the status of the calibration.
START CAL, CONFIRM (CR) Status is: ready for calibration.
Calibration may now be started:
*cal:quit (CR) Starts the calibration process.
OK (CR) Ecotec E3000 has received start signal.
