Brecknell 7010SB User manual

THE MODEL 7010SB ELECTRONIC SCALE
The model 7010SB electronic scale is a user friendly ten pound / 5000 gram
scale designed to to assist the operator in calculating the mailing costs of letters
and parcels for selected USPS classes of mail.
UNPACKING YOUR SCALE
Carefully unpack and inspect the shipping container for evidence of shipping
damage. If such evidence is discovered, stop unpacking and immediately notify
the shipper to arrange to have the shipment inspected by an authorized
representative. All damages must be promptly filed with the shipper.
1. Open the box and carefully remove the scale from the shipping carton (save
the shipping carton for future use).
2. Place the scale on a flat level surface free from vibration.
3. Remove the AC adapter and the RS-232 interface cable from the packaging
material.
4. Before using your scale please plug the scale into a power outlet and turn on
the scale for 10 minutes. This will allow the scale to warm-up and ensure
accurate weighing.
INSTALLING THE BATTERY
Use 9V ALKALINE BATTERY ONLY
No other type provides a suitable power output. The manufacturer
recommends Duracell MN1604 or Ever-Ready Gold Seal 6LF22.
To fit the battery, remove the cover on the underside
of the scale and push the connector firmly onto the
battery terminals. Refit the cover.

FUNCTION KEYS
The Model 7010SB has three function keys to operate the scale. The
ON(TARE), OFF, and lb-oz/ grams keys.
ON (TARE) KEY:
The ON key performs two functions. First it applies power to the scale; second it
tares the weight on the scale to zero. To use the “tare” feature:
1. Place an empty container on the weighing platform.
2. Press the ON key. Even though the container weight is on the weighing
platform, the scale will display zero weight.
3. When an item is placed on the container, the scale only displays the weight
of the item, not the weight of the container.
4. To reset the scale for no tare, remove the container and its contents from
the weighing platform. Press the OFF key, then the ON key to reset the
scale to zero weight.
(The tare function will work over the full weighing range of the scale but will not
extend the overall capacity of the scale.)
Important Note: It is recommended to press the “OFF key” then the “ON
key” before placing an item on the scale. This will help ensure accurate
weight readings.
OFF KEY:
This key turns off the power to the scale.
LB-OZ/ GRAMS:
The lb-oz grams key is to switch between weighing lb-oz and grams, it is also
used for entering into the calibration mode.
ZERO THE SCALE:
The proper method of zeroing the scale is to press the “OFF” key, then turn the
scale back on by pressing the “ON” key.
SLEEP MODE:
The default setting for sleep mode is Off ( SLP0). If there is no activity, the scale
will turn itself off after 30 seconds The sleep mode can be configured to On
(SLP1) via software.

Error Conditions – Shown in the scales display
Below are the error conditions that may appear on the scale display.
“- - - -“ Under Capacity
When the scale weight is below zero the scale will display all dashes (----) and
transmit a status for this condition. This situation will likely occur after the use of
tare when the tare weight is removed. To clear this indication, press the OFF
key, then the ON key and the scale will re-zero.
“Err” Over Capacity -
When the scale is in an overload condition the scale will also display “OvEr” and
transmit a status for this condition. In this case the weight applied to the scale is
above the 10-pound limit; remove the weight from the scale to clear this
indication.
“Lo” Low Battery-
When “Lo” is displayed replace the battery.
ErrL, ErrH, 8888:
The scale is damaged. If within warranty, return the scale to the factory.

SCALE CALIBRATION INSTRUCTIONS
Periodically your scale may require calibration to ensure proper weighing. You
will need a 10-pound weight to calibrate the scale. Scale calibration is
accomplished, when needed, by the following instructions:
Function Scale Response
1. Remove all weight from the scale
2. Press and hold the “ON/TARE” key and
press the “lb-oz/grams” key once . . . . . . . . . . . . . . . . . “SLP0/SLP1”
3. Press the “ON/TARE” once to accept the
sleep mode setting and enter into calibration mode. . . .”64XX – 10XXX”
4. Press the “ON/TARE” key once
to zero the scale. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .“0”
5. Place 10 lbs on the scale . . . . . . . . . . . . . . . . . . . . . . . ..“8,9XX - 10,000”
6. Press “ON/TARE” key once
To accept calibration weight . . . . . . . . . . . . . . . . . . . . . . .“CAL” then * “Err”
7. Press the “OFF” key to exit calibration mode.
8. Remove the weight from the scale, press the “ON/TARE” key to continue the
normal weighing mode.
* Note: The “Err” displayed after completing calibration does not indicate a
calibration error. Since, the scale only weighs up-to 9 lbs. 15.5 oz., the ten
pounds on the scale causes the displayed message “Err”.
