CONFIGURATION MENU Parameters
SEt ZEro
Parameter
The
SEt ZEro
parameter is meant to be accessible to the user. It allows the removal of fixed
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.
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 modes. 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 TR150, 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 at which you want the alarm to activate. When the alarm is activated, the word
OVErLOad
appears in the display. 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.
The 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 TR150 has a special power saving mode, which can be enabled or disabled within this
parameter. When asked whether you wish to select
P SAvE?
, pressing
will put the TR150
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.
