Calibration Procedures
The best method of calibration, if it is possible to do so, is the
LiVE
calibration, as this reads in the sensor signal at
two calibration points and scales the IHH200 automatically. If this is not possible, then the sensitivity figure (in mV/V)
from the sensor calibration certificate can be used to scale the IHH200 by using the
tAbLE
calibration. This may be
the only option available if you are unable to apply a known stimulus to the sensor, which quite often is the case.
LiVE Calibration Procedure
When
CALibrAt
is displayed press
.
LiVE ?
will now be displayed, press
.
You will be prompted
uSE SC ?
. This can be selected if you wish to use the shunt calibration figure from a sensor
calibration certificate (care should be taken that the shunt calibration resistor used originally with the sensor is the
same as is fitted in the IHH). If you wish to use this press
, otherwise press
.
You will then be prompted
APPLY LO.
At this point ensure that the low calibration stimulus is applied to the sensor
and allow to settle of approximately 3 seconds, then press
You then be prompted with
dISP LO.
Press
to enter the display value required with the low stimulus applied to
the sensor. The value can be entered by using the
and
button to select a digit and the
and
buttons to change the digit. When the value has been set press
.
You will then be prompted with
APPLY HI
(unless you chose to
uSE SC ?
, in which case jump to the next stage) At
this point ensure that the high calibration stimulus is applied to the sensor and allow to settle of approximately 3
seconds, then press
.
You then be prompted with
dISP HI
. Press
to enter the display value required with the high stimulus applied to
the sensor. The value can be entered by using the
and
button to select a digit and the
a
nd
buttons to change the digit. When the value has been set press
.
You should now see
donE
displayed. This means the calibration was successful, press
to the IHH200 to
normal operation mode, with the new calibration data stored. If you see
FaiLEd
, then you will need to
repeat the calibration, checking that you have completed the procedure in the correct order, and that the sensor is
connected correctly.
tAbLE Calibration Procedure
When
CALibrAt
is displayed press
.
LiVE ?
will now be displayed, press
.
tAbLE ?
will now be displayed, press
.
You will be prompted with
InPut LO
, press
.
