record (340i)
When calibrating with AutoCal TEC and AutoCal DIN, the AutoRead
function is automatically activated.
The current AutoRead measurement can be terminated at any time
(accepting the current value) by pressing <RUN/ENTER>.
Each time the instrument is switched on, the calibration data are shown
data on the display for a short time (see section 4.1 S
SURING INSTRUMENT
measuring instrument off and switch it on again.
The calibration protocol contains the calibration data of the current cal-
ibration. You can transmit the calibration protocol to a printer via the se-
rial interface (see page 40).
Note
You can automatically print a calibration protocol after the calibration.
To do so, connect a printer to the interface according to section 4.5.3
before calibrating. After a valid calibration, the record is printed.
