Salter Brecknell 335 Bedienungsanleitung

Model 335 Postal Scale

User Manual

1.1 Introduction

Designed for use within stable environments where fluctuation of

temperature, humidity and vibration are limited. The scale features a

weight hold function allowing you to view the weight of an item that is too

large and obstructs the weight display. The 335 also includes a units

switching function allowing you to weigh items in lb/oz, kg, or g.

Use the flip tray to weigh large envelopes or hold tubes/packages in place

on the weight tray.

The Model 335 includes a blue backlit display. The display will activate

upon power up and when the scale is in use for weighing. To save battery

life the backlight will turn off after seven seconds of no use.

The Model 335 Postal Scale,

shown at right, is an

affordable solution for many

applications. Perfect for use

in the office or home to weigh

letters and small packages.

The 335 includes a USB

interface that will provide

power and communication

with your computer and 3rd

party USPS software.

1.2 Unpacking the scale

Check packaging and scale for any obvious evidence of damage.

Immediately report shipping damage to Salter Brecknell.

Remove contents from packaging, your product should include:

1. Model 335 scale

2. One USB cable

If you are missing an item please contact you Salter Brecknell dealer for

immediate replacement at no charge, shipped via UPS ground.

1.3 Installing the scale

1. Mount the scale on a stable, level surface that is free from air

currents, rapid temperature changes and vibration. These may

affect the weighing accuracy or the stability of the displayed weight.

2. Carefully install, do not force, the weight platter on top of the

mounting posts. Make sure the weight platter does not touch any

adjacent surfaces.

3. Be sure all feet are in contact with the counter.

4. Plug the USB cable into the back of the scale and into a USB port

on a computer to supply power to the scale. You may use a 9v

battery, not supplied, to power the scale. See Installing or

Changing the Battery on page 3

5. Turn the unit on for five minutes, to allow the electronics and load

cell to warm up to room temperature.

6. Place a known weight on the scale to test the weighing accuracy.

Your scale should display the correct weight.

Troubleshooting Tip!

If your scale is not weighing accurately upon

installation, calibrate the scale. See Calibration

on page 9.

1.4 Operating Instructions

2. Remove the old battery.

3. Insert the new battery, making sure you align the battery into the

correct positive (+) and negative (-) orientation.

4. Replace the battery cover.

1.4.2 Annunciators and Key Functions

The 335 has a series of arrow annunciators along the bottom of the display

that point at labels to show you the current unit of measure, if the unit is in

Hold mode, if there is an active tare and if the scale is at zero weight.

Below are descriptions of the three key functions.

Key name Function

Hold / Unit Quick press this key to activate Hold mode. An arrow above Hold

will flash until weight is stable, then a beep sounds and the arrow

will remain lit. Place your item on the scale, allow two seconds for a

stable weight reading, Once you remove the item the weight will be

held in the display until you quick press the key again.

Press and hold for 3 seconds to switch to the next unit of measure

or continually hold to cycle through the units of measure (kg, g, lb,

oz). An icon above the kg, g, lb, oz label will light.

Zero / ON / OFF With the scale turned off and no weight on the scale, quickly press

this key to power On the scale. On power up the scale can zero up

to 10% of capacity.

To turn off, press and hold for more than 3 seconds.

1.7 Calibration

From time to time, all scales may require calibration to provide accurate

weighing. When calibrating your scale, you are teaching the scale a zero

reference point and a known accurate weight.

The MODEL 335 allows you to calibrate the scale using lb or kg weights.

1.7.1 Calibrating your scale using LB weights

1. Make sure there is no weight on the scale, and the scale is off.

2. Press and hold the Tare key, then press the Hold / Unit and Zero

/ ON / OFF key until the display shows 15.00 and release all the

keys.

3. Press the Hold / Unit key to calibrate the scale using a LB

weight…

35,0.0 is displayed. This is the amount of test weight you

need to calibrate the scale.

4. Press the Tare key to accept…

The scale will display the internal counts 9000—11000.

5. Press the Tare key to accept and to perform the zero calibration…

0,0.0 will be displayed briefly, then the internal counts will be

displayed again.

6. Place your 35 lb weight on the scale and press the Tare key to

perform calibration…

35,0.0 is displayed briefly, then the scale returns to normal

weighing mode and Err 2 is displayed.

7. Remove the weight from the scale and press the Zero / ON / OFF

key…

The scale will show 0,0.0 weight.

You must close any Windows program used

with the Model 335 before attempting to

calibrate the scale.

1.7.2 Calibrating your scale using KG weights

1. Make sure there is no weight on the scale, and the scale is off.

2. Press and hold the Tare key, then press the Hold / Unit and Zero

/ ON / OFF key until the display shows 15.00 and release all the

keys.

3. Press the Tare key to accept…

The scale will display the internal counts 9000—11000.

4. Press the Tare key to accept and to perform the zero calibration…

0.00 will be displayed briefly, then the internal counts will be

displayed again.

5. Place your 15 kg weight on the scale and press the Tare key to

perform calibration…

15.00 is displayed briefly, then the scale returns to normal

weighing mode and Err 2 is displayed.

6. Remove the weight from the scale and press the Zero / ON / OFF

key…

The scale will show 0.00 weight.

If CAL.Er appears, this indicates an error in

calibration. Repeat steps 1-7. If CAL.Er

continues to appear you may have a damaged

load cell or electronics.

WARNING! Calibrating your scale with

inaccurate or the incorrect weights as

defined in Stabilization Up to 2 seconds to

stable weight reading on page 11 will cause

your scale to weigh incorrectly.
