1.1. Features

The DI-28 Indicator offers a practical solution to a wide range of weighing applications.

There are a variety of weight capacities and increments available. The display resolution

is selectable from 1/2000 to 1/7500. It features RS-232 & 4 Setpoint outputs (factory

options) and keyboard calibration with auto-span. It operates on 6 “C” cell batteries or

with its AC/DC adapter. The DI-28 is able to support single load cells that have an output

range of 0.4mV/V to 4.0mV/V and is able to support up to 4 load cells when used with

the AC/DC adapter. This indicator features ON/OFF, REZERO, TARE, for both one

touch and digital key operation. A recharging circuit is incorporated for use with

rechargeable NiCAD batteries. For a list of platforms sizes and available capacities see

page 3.

This instruction manual will provide the user with all the information necessary to

understand, set-up and operate the DI-28 scale. Included in this manual are descriptions,

specifications, drawings, and operating instructions.

3.0. INSTALLATION

This section provides the information required for installation of the DI-28 weight indicator.

The following steps accomplish installation.

1. Unpacking

2. Set-up Procedure

3.1. Unpacking

Each component of the DI-28 is packed in a specially designed carton. Remove each

component from the carton, separate the component from its polystyrene shell assembly

and set aside. Inspect the carton interior to be sure that all accessories have been

removed from the carton. Inspect the carton inner panels for accessories.

NOTE: Be sure to repack all materials within the carton set. Store the cartons in a

secure area so they can be available whenever shipment of the scale is required.

3.2. Inspection

Immediately after unpacking, a visual inspection of the instrument should be performed.

If any damage has been incurred during transportation the shipper and DIGI MATEX

INC. should be notified immediately. Instructions for assessment of damage and further

procedures will then be determined.

3.3. Repackaging

If, at anytime, the DI-28 weight indicator must be returned for modification, calibration,

or repair, be sure that it is properly packed with sufficient cushioning materials.

Whenever possible, the original carton assembly should be retained for this purpose.

Any damage caused by improper packaging will not be covered by warranty.

3.4. Platform Unlocking Procedure

The unlocking procedure is different for each style of platform and is included on

the following pages.

3.5. Mini Grand Pole Assembly

The optional pole mounting kit comes with all the necessary hardware and assembly

is easy. See pages 8 & 9 for details.
