2. Outline and Features

These scales are designed to comply with IP-65 of IEC 529

The HV-WP series is a platform scale with 1/3000 resolution, and has a "triple

weighing range" function to select the weighing range.

The HW-WP series is a platform scale with 1/10000 resolution.

The scales have a fluorescent display so the weighing value can be read in dim light.

This type uses the AC power line as a power source.

Using the standard RS-232C serial interface, data can be output to a printer, and the

scale can be controlled or can be set by a command from a personal computer.

The counting mode function converts the total mass value (total weight) of articles to

be counted, to a count, when each of these articles assume the same mass value.

The scales can display the unit of percentage.

The accumulation function accumulates each weighing value and counts the number

of weighings using six figures.

The comparator function compares the display value with the upper limit value (HI),

lower limit value (LO) and displays the result. The result can be output by a buzzer if option OP-03 is installed.

The simple batch function or full/dribble batch function can be used for filling up to a

target mass value. The status of a weighing value can be output if option OP-03 or OP-04 is installed. The outputs are zero band, preliminary and final.

Using the optional RS-422/RS-485 serial interface and a computer, up to 16 scales

can be controled, if this option (OP-04) is installed in place of the RS-232C serial interface.

The following parameters are stored in the product with no power supplied.

Unit mass of the counting mode 100% mass of the percentage mode Total count and total mass of the accumulation function Upper limit value and lower limit value of the upper / lower comparator function, Final value, preliminary value and zero band of the full / dribble batch function or Final value, preliminary value and zero band of the simple batch function Calibration data Parameters of the function table (f1 ~ f17)

4. Caution

4.1. Precautions for Installing the Scale

Ground the scale, so that the user will not be subjected to an electric shock. Do not handle the Main power cord with wet hands. The AC plug is not water-resistant. Install it in an area where it does not get wet. Do not install the scale where there is flammable or corrosive gas present. Do not install the scale under water. Do not pull, fold or arrange cables forcibly.

Consider the following conditions to get the most from your scale.

The best operation is where the temperature and relative humidity is stable, the place to

install the scale is a solid and level floor, there is no draft and the power source is stable. Do not install the scale in direct sunlight. Do not install the scale near heaters or air conditioners. Do not install the scale near equipment which produces magnetic fields. Do not install the scale in a place where it is apt to be charged with static electricity, or

where the relative humidity is lower than 45%RH. Plastic and isolators are apt to be

charged with static electricity. Do not use an unstable power source.

4.2. Precautions for Operating the Scale

Periodically ensure that the weighing value is correct. Calibrate the scale before using and after moving it to another location. Do not place anything on the weighing pan which is heavier than the weighing capacity Do not drop anything upon the weighing pan. Do not use a sharp instrument such as a pencil or ball-point pen to press the switches.

Press the switches gently using only your finger. We recommend pressing the ZERO switch before each weighing to prevent possible error. Close the calibration switch cover and the display rear cover to keep waterproof.

4.3. Precautions for Storing the Scale

Do not disassemble the scale. Do not use solvents to clean the scale. For best cleaning of the display unit, wipe with a dry lint free cloth or a lint free cloth

which is moistened with warm water and a mild detergent. Do not scratch the base unit with a brash.

Do not use a powerful water jet.

Explanation

The status of "Inactive comparator (f6)" is that comparator function (f6 0, f6 2, f6 4, f6 6)

is selected and the comparator is not used. The "active" or "Inactive" (ON/OFF) for the comparator can be selected by pressing the SET switch alternately.

The following parameters are stored in the same memory. Therefore, the functions

can not be used at the same time. If you use each function, it will be necessary to select the function from the function table, to set the parameters of HI,OK and LO, to weigh it using the function.

10. Accumulation Function

This function counts the number of weighed items, calculates the total mass value

and can display the number and accumulated mass value.

The accumulation function is displayed with up to 6 digits. The balance can not display 7 or

more digits, therefore the leading digits are not displayed. Example: With 60K type, when importing the data of 17 accumulations of up to 60kg (60.000

X 17=1020.000), the balance displays this as “020.000”.

Set the parameters of the "accumulation function ( f8 )" in the function table, in

advance, to use this function.

The accumulation count and accumulated mass value are stored in the scale even if

the power is removed.

Operation and Switches

14. Calibration (Adjusting the Scale)

The scale is an instrument which measures the "weight" and displays its "mass" value.

Calibration is the adjustment function so that the scale can weigh correctly.

There are three steps to calibration.

Gravity Acceleration Correction ... When a calibrated scale is moved to a distant

place, the scale can correctly weigh anything by revising to a new local gravity acceleration.

Refer to the "Gravity Acceleration Table" on

the next page.

Calibration of the Zero Point ......... When there is nothing on the weighing pan, it is

the function that performs adjustment so as to display the zero point mark .

Comment The zero point, is the fundamental starting point

to weigh anything, influences the performance of scale.

Span Calibration.............................. The function that adjusts the span with a

calibrated mass so the scale can accurately weigh anything within the weighing capacity.

Comment Span means the range of weighing capacity.

Use a calibration mass heavier than two thirds of the weighing capacity.

Caution

Periodically check the accuracy of weighing. Calibrate the scale, if it is moved

to another location or the environment has changed.

It is not necessary to set the gravity acceleration correction, when calibrating

the scale with a calibration mass at the place where the scale is to be used.
