Quick Start User's Guide
Fig. 1: Model 7000 Front Panel Layout
Model 7000:
The Model 7000 (Fig. 1) controls consist of the ZERO and optional UNITS buttons
located under the main display. A six-digit LED display is used to provide weight
indications, negative polarity (except lb/oz) and operator messages describing scale
operation. A status annunciator, "NEG," is used to display negative polarity as well as
the minus sign (except in lb & oz). The "NEG" LED is located in the lower left corner of
the display area. Four LED's located at the bottom of the display indicate the current
weighing units. Motion is indicated when the units LED's are off. The LED's are on
when stable.

Model 7000XL:
The operational controls for the Model 7000XL (Fig. 2) consist of the ZERO,PRINT and
UNITS buttons. A six digit LED display is used to provide weight indications and
operator messages describing scale operation. Scale status such as motion (MOT),
polarity (NEG) and center of zero (ZERO) is displayed on annunciators located to the
left of the display area. Scale units are displayed on four annunciators located to the
right of the main display.
Fig. 3: Model 8000XL Front Panel Layout
Model 8000XL:
The operational controls for the Model 8000XL (Fig. 3) consist of the ZERO (on/off),
PRINT and UNITS buttons. A six digit LED display is used to provide weight indications
and operator messages describing scale operation. Scale status such as motion (MOT),
polarity (NEG), center of zero (ZERO), and low battery (BATT) are displayed on
annunciators located to the left of the display area. Scale units are displayed on four
annunciators located to the right of the main display.
Power Up:
Connect the Model 7000, 7000XL to a compatible power source. With the 8000XL,
press and release ZERO to turn on scale.

Basic Weighing Operation:
1) Remove all items from the scale platter.
2) Press ZERO to zero the scale. The weight display should now read zero.
3) Place an item on scale platter and wait for the motion (MOT) indicator to go out,
indicating a stable weight.
4) Read the weight on the scale display.
Turn Off: (8000XL)
1) To turn off manually, press and hold the ZERO push button until the display shows
"rEL Pb." Then release, the ZERO button and, the indicator will turn off, or…
2) Indicator will turn off automatically at the end of the unit on timer setting when that
mode is selected (see page 23).
Low Battery Indication: (8000XL)
The "BATT" indicator indicates that the battery is in need of recharging. Once the
"BATT" indicator turns on, there will be approximately one more hour of battery life
before the scale shuts down. When the battery is too low to run the scale, the Model
8000XL simply turns off and will not operate again until the battery is recharged. The
Model 8000XL remains accurate and useable even with the "BATT" indicator on.
Note:Battery life can vary depending on the following:
The operating temperature.
If optional remote display is installed.
Whether or not the battery is fully charged after each low battery event.
Load cell input impedance.
Electrical Connections:
Prior to connecting your Model 7000, 7000XL, 8000XL to power, check the serial
number tag on the scale for the correct operating voltage. Verify that the power matches
the rated voltage.
Be sure the AC power is not excessively noisy - this can occur if large inductive loads,
such as solenoids or motors, are on the same power line. The Model 7000, 7000XL,
8000XL has a filtered power supply to reduce the effects of normal line noise, but they
cannot limit severe fluctuations. If problems occur, noise producing devices may have to
be suppressed to minimize their effect.
Zero:
The ZERO push button is used to zero the scale prior to making a reading. The zero
button can function over the full range of the scale or it can be limited to a zero band
equal to 4% of scale capacity for Canadian Legal for Trade applications. To zero the
scale, wait until the scale is stable and press the ZERO button. The scale will zero
immediately. The scale will not "zero" if the scale is in motion. The scale is equipped
