1. General purpose weighing of mailable objects up to 25 pounds in weight.
2. Displaying weight of a single mailpiece, number of mailpieces per pound or number of pieces on the
scale after a number of identical pieces have been weighed.
3. Manual entry of a tare weight or automatic zeroing of weight on the scale, for purpose of using a
container for weighing.
4. Ability to display weight digitally in pounds and ounces or in pounds only.
5. Perform all of the above functions with an input from a remotely located weighing device.

1.3 Description of scale
The Detecto MSB-25 is a ruggedized, fully-electronic digital weight indicator employing a single-point load
cell, stainless steel weighing platform, digital electronics, full-travel keypad, LED annunciators to indicate
scale mode, twenty character alphanumeric dot matrix display with 7/16 inch high characters, and serial
interface. Operating instructions are readily visible on a pull-out instruction placard.
1.4 Principles of operation
The scale may be used to display weight; either gross weight or net weight (gross minus tare). Displayed
units may be either pounds or pounds-ounces format. Known container tare weight may be entered via the
keyboard. Unknown container tare weight may be zeroed off. An average weight per piece of identical mail
pieces may be taken from a known sample quantity. The sample quantity must be large enough to total 0.2
lbs of weight. The default sample quantity is 10 pieces, however a more convenient sample quantity may be
selected via the keyboard. The weight per piece or pieces per weight may be displayed. Number of pieces
(count) may also be displayed.

responsibility of the purchaser to file all claims for any damages or loss in
transit incurred, unless this responsibility has been accepted by the Seller
in its proposal.
3.2 PLACEMENT
Place the scale on a stable, vibration-free location away from direct
sunlight and away from any rapidly moving air source.
CAUTION!!! DO NOT place the scale on any unstable
cart, stand or table. The scale may fall causing injury to
the operator, and seriously damage the scale, or proper
operation of the scale may be inhibited.

3.4 POWER SUPPLY CONNECTION
3.4.1 Plug power cord into a grounded, 3-pronged wall receptacle that
supplies 115 VAC power. If an extension cord must be used, it should be
a 3-wire, grounded type.
3.4.2 If a 2-pronged wall receptacle is encountered, it is the responsibility
of the customer to contact a qualified electrician to replace the 2-pronged
receptacle with a properly grounded 3-pronged wall receptacle or to have
a grounding adapter properly installed.
CAUTION!!! - To avoid electrical hazard, DO NOT under
any circumstances, cut, remove, alter, or in any way
bypass the power cord grounding prong. Be certain
power cord is routed out of the way of normal traffic.
CAUTION!!! - If it becomes necessary to replace a fuse,
use only fuses of type 3AG 1/4 ASB for 115 VAC
operation. ALWAYS UNPLUG THE POWER CORD
BEFORE CHANGING THE FUSE.
3.4.3 START-UP
When the power switch is turned ON the scale will perform a brief display of
model and version numbers. On conclusion, the display will show zero
weight, signaling that the scale is ready for use.
When the unit is plugged in and turned OFF, power is provided to the load
cell and circuitry, so that the unit will be ready to weigh accurately
immediately after power-up.
If plugging the unit in after an extended period, allow the unit to warm up for
approximately 15 minutes.
