Section 3: Operation
3.1. Power-on
Because the scale uses special low-power circuitry, no warm-up time is
required. Weight readings will be accurate as soon as the unit is powered on
3.2. Keys
and set to zero.
When the unit is powered, the liquid crystal display (LCD) will show the
software part number and the revision followed by either "0.00", or "------".
Dashes are displayed to indicate the scale is registering a weight upon
startup. Press [ZERO] to set the display to '0.00' and start weighing.
The keys for operating the scale are located on the main display and on the
remote display.
1. Pressing the [ZERO] key resets the display to indicate zero (0).
• The zero range is set at 2% or 5.00 lbs. when set for Canadian use.
• The zero range is set at 100% or 250 lbs. when set for USA use.
2. The [ZERO] key function will be inhibited if the instrument detects any
of the following conditions:
• Motion on the platform
• An underload condition
• An overload condition
• Outside of programmed zero range
3. Pressing the [UNITS] key toggles the weighing units and annunciators
between “lb” and “kg”. Verify the units you want to use by noting the
arrow indicator on the display.
