hidden by a rubber plug. These two adjustments
must be done in order. Refer to the illustration
above when executing these procedures.

The final adjustment is the span. This is set by

adjusting the potentiometer nearest the front of

the scale.
The first adjustment is the zero offset. This is set

by adjusting

To adjust the zero offset value:

1. Press any key while turning on the power switch. The display blanks out and the triangle

indicators come on. Release the key.

2. Press the “1” key. The PIECES window shows the internal zero offset count.

3. With all objects removed from the stainless steel platter, adjust this value to 5,000 ± 20%

counts using the rear potentiometer. NOTE: To decrease this value, turn the trimmer
clockwise. To increase this value, turn the trimmer counter-clockwise.

4. Turn the scale off to exit this mode.

To adjust the span value:

1. Turn the scale on without pressing any keys and without any objects on the stainless steel

platform.

2. Place a test weight(s) on the platter closest to the full scale capacity as possible. Adjust

the trimmer nearest the front of the scale to “dial in” the correct weight value. NOTE: To
decrease this value, turn the trimmer counter-clockwise. To increase this value, turn the
trimmer clockwise.

3. Remove the test weight(s) and re-zero the scale.

4. Repeat steps 2 and 3 until the correct weight value is obtained from the scale.

Introduction

The CS Series Counting Scale, available in three
capacities, is an easy to use, high resolution
counting scale featuring keyboard tare and unit
weight entry, as well as a memory accumulator
and check function. Housed in a durable ivory­colored plastic enclosure, the unit displays its

Getting Started

After unpacking the scale, a small amount of assembly is required:

þ Locate the sub-platform, four (4) Hex screws, and enclosed Allen wrench. Place sub-platform onto

scale's load point with all rubber parts facing up. Install and tighten the four Hex screws.

Please Do...

þ Place the scale on a firm and stable floor or table.
þ Plug the line cord into an AC outlet.
þ Leave the scale on for at least 30 minutes before using. You will find the ON/OFF switch at the

bottom of the scale on the right, towards the front. You may leave the scale on at all times, if you
wish.

þ Press the ZERO key before operating the scale.

Unit Weight Indicates either the calculated or the keyed-in unit piece weight in thousandths

(0.001) of a pound.

Pieces Indicates the number of pieces currently on the platform.
Zero Indicates that the weight reading is at the scale's zero position.
Tare Indicates that the current weight reading is net weight.
Light Indicates that the unit weight is not high enough to display an accurate piece

count.

Tare Operation

In order to subtract the weight of the container or
vessel from the scale's reading, it is necessary to
enter that weight as the tare weight. This value
can be entered into the CS Series Counting
Scale by either the push button tare method or
the keyboard tare method.

To use the push button tare method:

1. Place the empty container on the platform.

2. Press the TARE key. The TARE indicator comes on and the WEIGHT display window shows zero.

To use the keyboard tare method:

1. Enter the known tare weight in pounds into the scale using the numeric and decimal point keys.

NOTE: You must enter all three decimal places if the tare weight is not in whole pounds, i.e. enter

1.2 lbs as 1.200 lbs. This value will be blinking in the UNIT WEIGHT display window.

2. Press the TARE key. The TARE indicator comes on and the WEIGHT display window shows the

keyed-in tare weight as a negative value.

A tare weight may be entered up to and including

the scale's full capacity, however the maximum

negative weight that the scale can show is -9.999

lbs.

For greater accuracy, it is suggested that the

push button tare method be used.

To clear the tare weight from the scale:

1. Remove all weight from the platform and press the TARE key. The TARE indicator goes off and

the WEIGHT display window again shows zero.

Possible Tare Operation Errors:

You cannot enter a tare weight that is greater
than the scale's full capacity. For example, for the
CS-12, you cannot enter, say, 13.000 lbs.

Also, you cannot key in a decimal point value
higher than the resolution of the scale. For ex-

ample, for the CS-12, you cannot enter 0.001 lbs.

since the resolution is 0.002 lbs.

In both cases, the scale will automatically reset

itself after three seconds, or you can press the

CLEAR key to key in a new value.

Piece Counting Operation

There are two ways to use the piece counting
operation. A unit weight value can be keyed into
the CS Series Counting Scale by using the
keyboard entry method. Alternatively, the

sampling method may be used.

Both the sample weight and the unit weight have

limits to assure accuracy. The limits for these are

found at the bottom of the page.

To use the sampling method:

1. Place a pre-determined number of pieces on the platform. The WEIGHT display window shows

the total weight.

2. Key in the number of pieces you have placed on the platform. This value will be blinking in the

UNIT WEIGHT display window.

3. Press the SAMPLE key. The UNIT WEIGHT display window now shows the calculated unit

weight, while the PIECES display window shows the actual number of pieces on the platform.

To use the keyboard entry method:

1. Key in the pre-determined unit weight in thousandths of a pound; i.e. enter 0.010 lbs as 10. This

value will be blinking in the UNIT WEIGHT display window.

2. Press the SET key. The UNIT WEIGHT display window now shows the keyed-in unit weight value.

To clear the unit weight from the scale:

1. Press the CLEAR key. The UNIT WEIGHT display window now shows zero.

Possible Sample Weight or Unit Weight Entry Errors:

Consult the table below for limits to both sample weight and unit weight. A light unit weight will still allow
counting operation, but accuracy cannot be guaranteed.

display window.

4. Press the M+ key to add this value to the accumulator's memory.

5. Repeat steps 3 & 4 until all pieces are counted.

6. Press the MR to view the contents of the accumulator. The display shows the information in the

PROBLEM:

1. Will not tare to zero.

2. When sample is placed on pan, display

reading will not stabilize, i.e. jumps one
or more divisions.

3. Display will not change after sample is

placed on platform.

4. Displayed numbers flash on and off and

scale will not tare.

5. No readout appears in the display win-

dows or the WEIGHT window does not
return to zero.

6. Display is stuck after power is turned on

and all digits show zero or are blank.

THINGS TO CHECK:

A. Proper warm-up time is at least 30

minutes. It is recommended that the unit
be left on continuously.

B. Large machinery may cause vibration in

the work area. The scale should be
placed on a stable surface.

C. Excessive air movement can affect

stability. Scale should be located away
from air conditioners, fans, fume hoods,
etc. A breeze shield may be required.

D. Extreme changes in room temperature

can affect the internal calibration of the
unit.

E. The sub-platform is held in place by four

screws which may vibrate loose. Re­move the platform to check. IMPOR-

TANT: DISCONNECT THE SCALE
FROM THE AC OUTLET PRIOR TO
REMOVING THE PLATFORM. Do not
over tighten screws.

F. Do not place the scale near magnetic

materials or instruments which incorpo­rate magnets in their design.

G. Power supply cord should fit snugly in

the socket.

H. The line voltage to the scale should be

reasonably constant and free from fluc­tuations. It is advisable not to share an
outlet with fluorescent lights or other
products which draw voltage in an in­consistent manner.

I. Where applicable, check for a blown

fuse. Replace with a metric 0.5 Amp
quick blow fuse. IMPORTANT: DIS-

CONNECT THE SCALE FROM THE
AC OUTLET PRIOR TO REMOVING
THE FUSE.

J. A/D converter is not stable or load cell

has failed. Return scale for repair.
