1. INTRODUCTION
1-1. Introduction
Thank you for your Purchase!
This manual describes the functions of your counting scale and how to get the most out of it. Read this manual carefully before use.
Features
The HC-i counting scales have the following features:
The scales have the high internal resolution for a wider range of counting applications.
HC-3Ki / 6Ki / 30Ki: 1/600,000
HC-15Ki: |
1/750,000 |
There are the following ways to enter a unit weight (of the sample piece).
The way to weigh a fixed number of samples like 5 pieces, 10 pieces and so on.
The way to weigh the desired number of samples.
The way to store the desired unit weight directly using the 10-key pad.
The way to recall the stored unit weight from ID memory.
The way to send the desired unit weight from a personal computer.
Three UNIT WEIGHT BY LED's will navigate you to enter a unit weight easily.
ACAI (Automatic Counting Accuracy Improvement) supports counting by recalculating the unit weight when a sample is added. Therefore it is possible to reduce the counting error.
The scale can show information for piece count, weight, unit weight and comparator result at the same time.
UP to 99 ID memories can store ID numbers, unit weight, tare weight and comparator limits.
Comparator function:
Compare a count or weight
Comparator limits can be changed using the 10-key pad.
Comparator relay output is also available using an optional interface.
Accumulation function for counting.
Optional RS-232C interface to communicate with a personal computer and printer expanding the counting application.
The optional SLA (sealed lead acid) battery is useful for portable operation.
3
1-2. Unpacking
Unpack the scale carefully and keep the packing material if you are likely to transport the scale again in the future.
In the carton you should find this manual plus:
The counting scale.
An AC adapter (check that the AC input rating is correct).
Remove the protective packing materials from around the scale and between the pan and scale casing.

1-4. Setting Up Your Scale
1.Place the scale on a suitable weighing surface (see “Best Conditions For Weighing” below) and turn the adjustable feet until the spirit level shows that the scale is level.
2.Plug in the AC adapter. The AC input
requirements could be l00, 120, 220,
230 or 240 Volts (50/60Hz) depending on the area in the world so please check that the adapter is correct. Earth the chassis if you think static electricity may be a problem.
3. Press the ON/OFF key to turn the power ON.
All the display symbols are displayed.
AC adapter jack
Earth terminal
Then the display turns off once, and zero will be shown with the ZERO mark.
4. Pressing the ON/OFF key again, and the power will switch OFF.
Auto-power off function
It is possible to have the power automatically switched OFF. If zero is displayed for approximately 5 minutes. See “9-2. F-Functions” and set the F-Function f-04-05 at “1” to enable the function.
5.Switch the power ON at least half an hour before use so that the scale can warm up.
Best Conditions For Weighing
The Scale must be level (check the spirit level on the scale).
Best operating temperature is between 20°C~25°C / 68°F~77°F at about 50%~60%
Relative Humidity. There shouldn’t be large temperature fluctuations.
The weighing room should be kept clean and dry.
The weighing table must be of a solid construction.
Corners of rooms are best as they are less prone to vibrations.
Don’t install the scale near heaters or air conditioners.
Don’t install the scale in direct sunshine.
Try to ensure a stable AC power supply when using an adapter.
Keep equipment containing magnets away from the scale.
Warm up the scale more than 30 minutes before use.
Ground the scale chassis for electrostatic discharge if the weighing conditions warrant.
Calibration
Calibration of the HC-i is required when the scale is initially installed. Please see “8. CALIBRATION” for more calibration information.
5
1-5. Simple Operation Mode
If desired, the HC-i scale can be set in a Simple Operation Mode. Set the F-Function f-01-01 at “1”. In this mode, only front panel keys that would be used in “3-3. Unit
Weight By a Sample” counting operations are active. All others will not operate. The following keys are active in Simple Operations Mode:

Set F-Function f-09-01 to “2” and you can change the weighing units between “kg” and ”lb” by using the ½ key.
1-7. Last Unit Weight Used Feature
There are a number of ways to register a unit weight to count. The HC-i scale has a feature to keep the last unit weight used in memory. This can be handy if you turn the scale off and then want to return to the same unit weight, or you accidentally clear the unit weight by pressing the RESET key.
When a unit weight is registered it is automatically placed in the ID “id-00” and remains there until a new unit weight is entered. It can be recalled by the following:
