4.2 Description of the front
In addition to the front keys described in the previous aside,
there are 2 alarm warning lights labelled as AL1 and AL2.
4.3 Starting
On connecting the power supply, the instrument shows the
message
tESt
moving through the displays while all the internal
parameters are started.
4.4 Loss of power supply
All of the working parameters of the instrument are stored in an
internal memory. When the power supply returns, it will return to the
operating mode in which it was before.
4.5 Automatic calibration of the pressure transducer
This indicator has an automatic self-calibration function for
pressure transducers that enable this. In the AK-32, this function is always
available, whereas in the AK-30 it is only available when the input probe
is set up as a pressure transducer
InP
= 13 ).
To activate the self-calibration, the must be held down for 3
seconds. Firstly, the zero value of the transducer is calibrated, and then
the value of 80% of the scale base. If the transducer is subject to pressure
when the zero value is calibrated, the calibration will not be correct.
At the end of the self-calibration, the message
SAUE
appears if
the measurements taken are correct. By pressing the new calibration
is confirmed, whereas by pressing
, it is discarded. If the
measurement taken in the zero and that taken at 80% of the scale base
are not correct, the
FAiL
message appears.
