Configuration Menu Parameters
SEt ZEro Parameter
The SEt ZEro parameter is meant to be accessible to the user. It allows the removal of fixed display offset values from
the display, so that the GROSS and NET features can operate from a zero point. This may also be considered as a
manual tare facility. To zero the display, simply enter the value that you wish to subtract from the display in the SEt
Zero parameter. i.e. if the display reads 000.103 and you wish it to read 000.000, then enter 000.103 in the SEt ZEro
parameter.
Set Zero may also be achieve by pressing Gross/Net and Shunt Cal button simultaneously.
Different values can be set for each RANGE.
SEt rAtE Parameter
The SEt rAtE value sets the display update rate. The options available are 25Hz, 10Hz, 3Hz, 1Hz and 0.5Hz. Different
updates rates can be set for each RANGE.
The 25Hz rate only updates at this rate when in the PEAK or TROUGH mode. When in normal display mode it has
been limited to a 3Hz update, as the digit fluctuations are impossible to view with the human eye.
The 10Hz, 3Hz, 1Hz and 0.5Hz rates update the display every 100mS, 300mS, 1000mS and 2000mS respectively.
The IPM25 when it leaves the factory is set at 3Hz.
SEt OVEr Parameter
The SEt OVEr parameter allows the user to set a visual alarm. The value that is entered is the display value that you
want the alarm to activate at. When the alarm is activated the word OVErLOad appears on the screen. To remove the
alarm, the display value must be reduced to a value that is lower than that set in the SEt OVEr parameter. This can be
very useful as a safety feature, or simply as a quick indication of when a preset level has been reached.
This value entered can be anywhere over the entire display range, so there are no limitations. Different values and
settings are available for each RANGE.
SEt OPEr Parameter
The IPM25 has a special power saving mode, which can be enabled or disabled within this parameter, pressing
when asked whether you wish to select P SAvE? will put the IPM25 into power save mode for the RANGE selected.
Pressing
will de-activate the power save facility.
When the power save facility is activated, battery life is conserved by pulsing on the excitation voltage to the sensor.
As a result the accuracy is reduced, as is the update rate. When in this mode, the quickest update rate is 3Hz and the
accuracy of the display is reduced to 1 digit in 10,000. It is important to note these limitations when deciding whether
to use the power save facility. However, it is also possible to set one RANGE with power save activated and the other
without.
The benefit is that the battery life, based on a 350 sensor bridge being connected, increases from 45 hours to 450
hours.
It is also important to remember that when the IPM25 is re-calibrated with a sensor, the power save facility will be
automatically turned off. The power save facility will therefore need to be re-activated after calibration has been
completed.
AUtO OFF Parameter
The AUtO OFF parameter is another power saving feature. It allows for the setting of a time period in minutes,
between 05 and 99 (00 de-activates AUtO OFF). i.e. if this was set to 25, then if the IPM25 detects no keyboard
activity for a continuous 25 minute period, then the IPM25 will power down, to conserve power. If keyboard activity is
detected at any time during the 25 minute period, then the time period is restarted.
This can be a useful feature in a site environment, should the IPM25 be left unintentionally powered on.
