WARNING
Use only the AC adapter which comes with the scale. Other adapters may cause damage.
(AC adapter is optional).
Internal service to this product should be performed by a qualified person only. There are
no user serviceable parts inside.
CAUTION
Avoid installing the scale in areas of direct sunlight and high humidity. Also avoid drafts, vibrations
and dusty conditions.
Do not mix the type of batteries. Replace all batteries at the same time.
If the scale is not to be used for a long period of time, remove all batteries from the battery compartment to avoid leakage which may cause damage to the instrument.
To extend the life of your digital scale, do not drop items to be weighed onto the platform or overload the scale beyond its rated capacity. Shock-loading and overloading may damage the load cell
and void the warranty.
NOTICE:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the instructions
manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his/her own expense.
This device corresponds to requirements stipulated in 73/23/EEC and features radio
interference suppression in compliance with valid EC Regulation 89/336/EEC. Note: The

Getting Started
1. Plug the optional AC Adapter into the scale first, then into an AC outlet. For portable operation, install 6-AA size alkaline batteries in the battery compartment located underneath the
scale.
2. Place the scale on a stable and firm table.
3. Press the ON/ZERO key. All segments will briefly appear, followed by the version code and
finally an indication of zero weight. The scale is now ready for use.

Operation
How to obtain the weight of an item:
1. Before weighing an item, make sure the scale shows a zero weight indication. If it does not,
remove all items from the platter and press the ON/ZERO key.
2. Place the item on the center of the scale’s platter and allow the weight indication to stabilize.
3. Select the desired unit of measure by pressing the UNITS key.
Sample operation:
1. At any time, press the SAMPLE key. The scale displays the message “10 0”. This is the sample size.
2. Add ten identical pieces. The scale shows “10 –“.
3. Press the
SAMPLE
key again. If the items are heavy enough, the scale is in pieces mode
and displays ten pieces with no annunciator. If there is a sampling error, the scale briefly
shows “Add” then updates the sample size first to 25 pieces then to 50 pieces. If the operation
fails for 50 pieces, then the parts are too light for the scale to process at all.

Err 2
“- “
O L
Indicates that the weighing capacity of the scale has been
exceeded.
Indicates that the batteries need to be replaced.
Indicates that there is not enough internal resolution to calculate the unit weight of an item. This means that the items
you are counting are too light for the scale to process at all.
Indicates that the unit weight of the items you are sampling is
too light for the scale to process accurately.
The scale’s calibration information has been lost. Recalibrate scale.
Indicates that the negative number is beyond the display’s
capability (-99.9 or –15.9).
Indicates that the lb-oz display is greater than 9 lb 15.9 oz..

Calibration
Your 302-BP Series scale is ready to use right out of the box. There is no need to calibrate the
scale unless you feel that the scale has become inaccurate. It is a good idea to check the calibration of your scale from time to time with a precision test weight. Transcell recommends that you
perform a new calibration on your digital scale at least once a year. The 302-BP must be calibrated with a precision test weight equal to the capacity of the scale. See Page 2 for the product
matrix list.
To calibrate the scale:
1. Remove all items from the platter and turn the scale OFF. Press and hold the SAMPLE key
while turning the scale back ON.
2. The scale shows “CAL” briefly then “ZERO”.
3. Press the ZERO key. The scale then shows “ADD”.
4. Place the appropriate test weight on the platter and wait for scale to show “SAVE”.
5. Press the MODE key to save the test weight calibration value.
6. Once the test weight calibration value has been saved, the scale shows an “End” message.
7. You must now turn the scale OFF and then turn it back ON without pressing any keys. Your
ESW is now calibrated and ready for use.
