The primary functions provided are detailed below.
2.2.1
Display range
The weight indicators will display weight from –Max to Max (gross weight) within the limits of the
display capacity.
2.2.2
Zero-setting
Pressing the "ZERO" key causes a new zero reference to be established and ZERO annunciator to turn
on indicating the display is at the centre of zero.
Semi-automatic zero-setting range: ±2 % of Max.
Automatic zero-tracking range: ±2 % of Max.
Initial zero-setting range: ±10 % of Max.
Zero-setting is only possible when the load receptor is not in motion.
2.2.3
Zero-tracking
The indicators are equipped with a zero-tracking feature which operates over a range of 4 % of Max
and only when the indicator is at gross zero and there is no motion in the weight display.
2.2.4
Tare
The instrument models are provided with a semi-automatic subtractive tare feature activated using the
"TARE" key.
When the tare function is active the "G/N" (BG) key will toggle the display between showing Net and
Gross value.
2.2.5
Printing
A printer may be connected to the optional serial data port. The weight indicator will transmit the cur-
rent to the printer when the "PRINT" key is pressed.
The printing will not take place if the load receptor is not stable, if the gross weight is less than zero,
or if the weight exceeds Max.
2.2.6
Check weighing
The indicator can be set to check the actual weight against a high and a low limit by the user pressing
"Unit" and "M+" key simultaneously and then setting the appropriate parameters.
2.2.7
Weighing unstable samples
The indicator has a special mode for weighing unstable samples. As this mode is a configuration mode
switching between this mode and normal weighing mode is not possible, when the indicator is sealed.
2.2.8
Display test
A self-test routine is initiated by pressing the on/off key to turn the instrument off, then pressing it
again to turn the instrument on. The test routine turns on and off all of the display segments and light
indicators to verify that the display is fully functional.
