Chapter 1: REFERENCE
The “Reference” chapter describes the major components of the Model 675 Precision Scale. Keypad functions, load
cell installation, display and connections are described in this chapter.
Enclosure
The enclosure is made of die cast aluminum with rib enforcement. This design provides extra strength and
durability. The enclosure is painted with powder coat finish and the counting surface is stainless steel. The enclosure
also includes built in carrying handles and a line cord wrap for ease of portability.

Load Cell
The load cell can be exchanged by removing two M6 1x 20mm (size) bolts from the bottom plate and two M6 1 x
16mm (size) bolts from the top spider assembly.
The load cell cable connects to J15 of the main board. The J15 connector is accessible from the load cell cavity of
the Model 675 enclosure
Figure 2: Model 675 Load Cell Installation
Install the new load cell by placing it in the load cell cavity. Fasten the load cell by installing the bolts on the
bottom plate. Reinstall the spider assembly.
NOTE: When exchanging a load cell with another, the overload stop and corner overloads must be reset. See Table
1 for specifications.
Table 1: Load Cell Overload Stops
Load Cell Stop Set to
Load Cell Center Overload 120 % of full scale
Corner Overloads 60 % of full scale
Display
A large 16 line x 40 character graphic LCD provides excellent visibility with user defined help screens and
prompting. The large graphic display features a backlight for use in poorly lit areas.

Jand KPress at the same time to backspace during an alpha entry.
ALPHA ENTRY
The Model 675 provides quick and easy alpha entry. The [ALPHA] key becomes the “Alpha enable/disable” key.
The alpha characters assigned to each numeric key mimic a telephone layout with the addition of the [0/space]
key. This allows additional ASCII characters to be accessed via the decimal point key. The display will show ™
while an alpha entry is in progress and > when the “Alpha” entry mode is disabled. If the ALPHA graphic icon is
enabled, it will also show on the display if an alpha entry is in progress.
Character Entry
When alpha characters and other non-numeric characters are to be entered using the front panel keypad, use the
[ALPHA] key to "build" the entry:
Press the [ALPHA] key to initialize the alpha entry mode. ALPHA will be shown on the display, indicating the
[ALPHA] key is active. Press the [ALPHA] key again to turn alpha entry off.
Keys [2] – [9] have uppercase and lowercase alphabetic characters assigned to them. The [ . ] key scrolls through the
remaining characters. The [0/SPACE]is used for inserting a space. Press the [CLR] + [0 /SPACE]keys
simultaneously to backspace one character.
To enter characters, press the corresponding number key on the keypad. The first character in the sequence
(depending on the “Alpha” mode selected) will appear first. Continue pressing the key before the timeout occurs to
scroll through the characters for that key. Refer to Table 2 for character key assignments.
