3.0. INSTALLATION
This section provides the information required for installing this counting system
For operation. The following steps accomplish installation.
1. Unpacking
2. Set-up Procedure
3.1. UNPACKING
Each component of the DC-180 system is packed in a specially designed carton.
Remove each component from its 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 future shipment of the scale is
required.
3.2. INSPECTION
Immediately after unpacking, a visual inspection of the scale should be performed.
If any damage has been incurred during transportation notify the shipper and DIGI
MATEX, Inc. immediately. Instructions for assessment of damage and further
procedures will then be determined.
3.3. REPACKAGING
If, at anytime, the DC-180 counting scale 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.
3.1. UNPACKING
The unlocking procedure is included on the next page. The DC-180 should
be properly locked whenever it is being transported.

3.4. Unlocking Procedure (Continued) for 5LB. To 50LB. Scales
INITIAL SET-UP PROCEDURES
Before setting up the scale, remove the load cell locking screws
located at the bottom of the scale as shown in the diagram below.
To Lock Scale for shipping:
1. Install cap screw finger tight.
2. Install allen screw finger tight,
3. Then install nut, just snug.
Do the following steps before scale calibration.
A) Place the platter on the platter support of the scale.
B) Turn on the power and check that the scale is functioning.
C) For calibration of the scale, use a thin rod to enable the span switch.
Refer to the diagram above for the location of the span switch.
D) Please refer to instructions for Span Adjustment for more detail.
Note: For DC-180 with a remote scale, connect the remote scale before plugging the A/C.
Warning!
Do Not Turn Scale Upside Down.
DISCONTINUED

Do not unplug remote scale from the DC-180 while the DC-180 is powered.
3.4. Unlocking Procedure (Continued) for 1LB. and 2.5LB. Scales
The above drawing is for illustration
purpose only.
SET UP PROCEDURES
Do the following steps before
scale calibration or operation.
1. Take off nut (A) and four screws (C), then take off plate.
2. Loosen nut (B) and screw (D) , then take off screw (D) , nut (B) and insert.
3. Take off screw (E) and stopper, then take off screw (F).
4. Install platter support and platter.
(Please pay attention to installation direction of support.)
Warning!
Do Not Turn Scale Upside Down.

4.0. DC-180 AC / BATTERY OPERATION
The DC-180 can be operated with AC power or with the optional internal
battery. The battery will automatically charge whenever the scale is
plugged into AC power. The charging current is regulated by a battery
monitor circuit, so that the battery can not be overcharged.
The DC-180 system is powered internally at a low power level whenever
the scale is plugged into the AC line or the battery switch is in the “ON”
position. The battery power switch is located on the right side of the rear
panel. The front panel “ON/OFF” switch enables the display and
primary power.
When the battery switch is “ON” and the AC is not connected, a low level
battery current will flow even if the display is “OFF”. To prevent battery
discharge when stored turn the battery switch to “OFF” whenever unit is
not used.
Do not store the scale without turning off the battery power switch.
To Install Battery Option
1. Turn Scale On Side.
2. Remove Battery Compartment Cover.
3. Connect The Red Lead To (+ ) Positive Terminal Of Battery.
4. Connect The Black Lead To ( −)Terminal Of Battery.
5. Place Battery Into Compartment & Replace Battery Compartment Cover.
CHARGING TIME: FOR OPTIMUM USE AND BATTERY LIFE, THE DC-180 BATTERY
SHOULD BE FULLY CHARGED BEFORE EACH OPERATING RUN.
NOTE: Short Cycle Charging Will Reduce The Normal Use Time And Can Drastically
Reduce Battery Life.
The BP-180 battery is a sealed lead acid battery which needs to be charged
periodically, similar to a car battery, if the BP-180 is left on the shelf for several
months without being charged it will eventually drain to point that it can no longer be
charged!

5.0. Operation Guide in Weighing Mode
5.1. Tare Reduction :
5.1.1. One Touch Tare Operation :
1 Display in the weighing mode
2 Place 0.5 Lb weight on the platter. (Example : of a .5lb tare)
3 Press the [TARE] key to tare the weight on the platter
4 Remove the weight from the platter
Note : The tare operation is valid up to the 4th digit of the weight column. For Example ;
when we attempt to tare a weight of 1.0000 lb, on a 5.0000 lb machine, the error buzzer
comes on. So, the maximum permissible tare value is 0.9995 lb. But for a 10.000 lb
machine, the maximum permissible tare value (for 100 % FS setting) is 9.998 lb.
5.1.2. Digital Tare Operation :
1 Display in the weighing mode.
2 Enter [0][.][5][0][0][0] (Example : of a .5lb tare)
3 Press the [TARE] key to tare the weight entered by keyboard.
Note : The same note as in One Touch Tare applies for Digital Tare as well.
5.2. Net/Gross Operation :
1 Display in the weighing mode.
2 Place 0.5 Lb. weight on the platter.
3 Press the [TARE] key to tare the weight on the platter.
4 Place an additional 0.5 Lb. on the platter.
5 Press the [NET / GROSS] key. 1.0000 lb is the Gross Weight.
6 Press the [NET / GROSS] key. 0.5000 lb is the Net Weight.

4 The Unit Weight Display shows the Unit Weight of the samples (1.255/1000 pieces) and the
Quantity Display shows the Quantity of the pieces i.e. 10 in this case.
Note : When the samples are placed on the platter, if the insufficient lamp is “ON”, then add
few more samples until the insufficient lamp is “OFF. Now, before pressing the [PIECES]
Key, enter the no. of samples using the key board and then press the [PIECES] Key. For e.g. :
After putting ten pieces of the sample, if the insufficient lamp is “ON”, then add few more
samples (say 3) until the insufficient lamp is “OFF”. Now using the key board, enter[1] [3] and
then press the [PIECES] Key to compute the Unit weight of the samples.
5.3.2. Unit Weight Operation by Key Entry :
