INTRODUCTION
This manual applies to the Doran Models 7000 and 7000XL Digital Scales. Operation of both scales is
very similar, with the 7000 providing the ultimate in simplicity. The 7000 has a single push button;
ZEROZERO which is used to clear (tare) the scale display. The 7000XL is an upgraded version of the 7000
providing additional operator control with a three button touch panel. This touch panel offers ZEROZERO,
which clears (tares) the scale display, UNITSUNITS to change the weight display units and PRINTPRINT to send
weight data to an external device. Both scales incorporate state of the art microprocessor technology
with software to give you the user a low cost solution to your everyday weighing needs. Designed for
ease of use, the 7000 and 7000XL can be quickly setup and ready for use.
Because both scales use the same electronic design, and share common features, Doran Scales Inc.
has combined the operating manual for the 7000 and the 7000XL. Where there are differences
between the operation of the two scales, this manual will describe the differences for your convenience.
Please read the manual carefully noting that information which applies to your scale.

Doran 7000 or 7000XL. If questions arise, please feel free to contact the Doran Scales Technical
Service Department at 1-800-262-6844.
NOTE: The National Conference on Weights and Measures has adopted an NTEP administrative procedure
entitled "Policy on Remanufactured and Repaired Devices." This policy states that a scale must be
repaired consistent with the original manufacturer's design. Failure to do so, will negate the NTEP
Certificate of Conformance.
All scales produced by Doran Scales Inc. use only the highest quality components. Many of these
components are manufactured to Doran Scales specifications and are not available from other sources.
In the unlikely event that your Doran scale requires service, protect your Certificate of Conformance by
insisting that your dealer service your scale with only Doran factory parts.

Section 1. Unpacking and Installation
UNPACKING
Before unpacking your Doran scale, please read the instructions in this
section. Your new scale is a durable industrial product, but it is also a
sensitive weighing instrument. Normal care should be taken when
handling and using this product. Improper handling or abuse can damage
the scale and result in costly repairs that may not be covered by the
warranty. If you notice any shipping damage, notify the shipper
immediately. Please observe the following precautions to insure years of
trouble free service from your new scale.
!DO NOT drop the scale indicator or scale platform.
!DO NOT immerse the scale indicator or platform.
!DO NOT drop objects on the platform.
!DO NOT pick up the scale platform by the "spider. "
Carefully remove the scale from the shipping carton. Be sure to retain all
shipping materials in case the scale must be shipped elsewhere.
INSTALLATION:
Locate the desired position for the scale indicator. If the indicator is to be
permanently mounted to a wall, shelf, or counter, remove the mounting
bracket from the indicator. Use the two holes provided in the bracket to
affix it to the desired surface. Before mounting the indicator into the
bracket, connect the scale platform and any data cables to the indicator.
Insert one of the threaded case studs into one of the mounting holes on
the bracket. Now gently spread the sides of the bracket apart and insert
the other case stud into the hole on the opposite side. Loosely thread the
two knobs back onto the studs. Adjust the indicator to the desired viewing
angle and tighten down the knobs.
ELECTRICAL CONNECTIONS:
Your Doran scale requires 115 Vac, 50/60 Hz power (230 Vac 50/60Hz.
power optional). 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 and Model 7000XL have filtered power
supplies 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.

Figure 2: 7000 Front panel layout and button locations.

Model 7000XL:
The operational controls for the Model 7000XL consist of the ZERO,PRINT and
UNITS buttons. A 6 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) 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.
Model 7000:
The Model 7000 controls consist of a single ZERO button located under the main
display. A single status annunciator, "NEG, " is used to display negative polarity. This
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.
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 1.9 % of scale capacity for Legal for Trade applications.
To zero the scale, wait until the scale is stable and press the ZERO button. The scale
will zero immediately. Neither the 7000XL or the 7000 will "zero" if the scale is in motion
or if it is outside of the 1.9% Legal for Trade zero band (when activated). Refer to
Section 4 of this manual for more details.
The 7000XL and the 7000 are equipped with an optional "Zero on Demand" feature
which holds "zero" requests until motion stops and capacity limitations have been
corrected. These options are activated during the scale setup procedure. Refer to
Section 4 of this manual for more details.
UNITS :
(Standard on the 7000XL, optional on the 7000)
The UNITS button provides the operator with the ability of changing the scale units by
pressing a button. The units indicator will immediately display the new units. The next
display update will indicate the correct weight in the new units.
The UNITS button has several configuration parameters which can disable the UNITS
button or limit the display units available. Refer to Section 4 of this manual for more
details.
PRINT:
(Standard on the 7000XL, optional on the 7000)
The PRINT button allows the operator to print the current weight by pressing a button.
Like the ZERO button, the user waits until motion stops before pressing the PRINT
button. The current weight will then be transmitted to the printer.
The PRINT button has a "Print on Demand" feature which stores PRINT requests until
the scale is stable. Once stable, the scale will transmits the current weight to the
printer. Several automatic print options are also available to simplify printer operation.
Refer to Section 4 of this manual for more details.
