34
This command displays the Auto Zero flag value. The value of 1=ON and
0=OFF. To turn auto zero tracking off enter 0 followed by the [TARE] key.
An invalid entry will display error 4.
23 Auto Zero Tracking Window (AZSM) (60)
This command displays the percentage of a graduation that can be tracked off
during zero tracking. Enter the value followed by the [TARE] key. This value
can be the following:
1-99: to track 1 to 99% of d.
100: to track off 1d.
200: to track off 2d.
300: to track off 3d.
To turn off zero tracking use parameter 22 above. Any other value entered will
display error 6.
45 Power up zero IZSM (0)
When this parameter is set to 1 the indicator will zero the scale automatically
on power up. The maximum range the scale will zero on power is set to +-10%
of full scale capacity. If the initial load on the scale exceeds 10% of scale
capacity then no initial scale zero will take place. Enter 1 to enable or 0 to
disable.
8.5 Parameters related to SCALE CALIBRATION
7 Scale Units
Toggles between pounds and kilos. Make sure that you have selected the units
you are calibrating with. If your test weights are in pounds or kilos then make
sure that the scale units illuminator is displaying the correct units.
11 Indicator Load Cell voltage range (39mV)
This parameter adjusts the input range for the scale-input channel. It is
important that the correct range be selected for optimal performance of the
indicator. Use values 1 to 3 to select the following input ranges:
1 for 0 to +-9mV input range
2 for 0 to +-19mV input range
3 for 0 to +-39mV input range
4 for 0 to +-79mV input range.
If the loadcell input voltage exceeds the input range of the indicator the
display will display ‘AAAAAA’ which means “Analog over-range”. Select the
next highest input range to rectify the problem. Only values 1 to 4 can be
entered and any other value will display error 57. It in important to understand
that selecting a lower input range, for example 9mV range does not necessarily
guarantee better performance. The 9 mV range has more amplification that lets
say the 19 mV or 39mV range. You will get more AD counts for sure, but you
are also amplifying noise. This depends on the scale installation. It most cases
the default 39mV or 19mV range will be adequate.
12 Deadload Scale
Before spanning the indicator for the first time the indicator must be
deadloaded. Ensure that the scale has all test weights removed from the scale
