INTRODUCTION

Ｔ hank you for your HB8215/HB8216 loadcell indicator purchase.

The HB8215 and HB8216 are the best choice for industrial weighing

application requiring quality, performance and economy. Please read

this instruction manual before operation to achieve the best

performance of the HB8215 or HB8216 and to operate it correctly.

Ｔ his operational manual is composed of four chapters and one

appendix. The first chapter of this manual provides the main

features and specifications of the HB8215 and HB8216. Chapter 2

presents the outline, panel descriptions and installation of the

HB8215/HB8216. In Chapter 3 the F-Functions of the HB8215/HB8216 is

introduced. Chapter 4 is devoted to the very important topic of the

HB8215/6 application for the various type of weighing. Finally, the

display messages of the indicator are given in Appendix A.

Ch.４ Applications

４.１ Tare Weight Setting :

1. Press TARE Key :

The [TARE] key zeros the net weight display and stores the

gross value into the tare weight memory. You can put some thing

which you want to be tared on the weigher and press [TARE] key to

tare it. (Net Weight = Gross Weight - Tare Weight)

2. F-Function Setting : F00

The indicator allows the user to enter a numerical value as the

tare weight directly via F00. An error message〔E r r F 0 0 〕

will be displayed, if the setting value isn't a multiple of the

minimum division or the setting value is greater than the maximum

capacity.

3. Tare Reset : (the tare value = 0)

<1>. Press [TARE RESET] key as the weight value is displayed.

<2>. Enter a 0 value via F00.

4. TARE LED :

● TARE : Turns on after a tare weight has been stored in memory.

Net Weight = Gross Weight - Tare Weight

○ TARE : Turns off when the weight is equal to 0.

Net Weight = Gross Weight

４.２ General Function Settings (F01～F08) :

F01 : Auto Net Weight Display

The "Auto Net Weight Display" function can be set on or off

via F01. When the "Auto Net Weight Display" function is set

on, the indicator will switch to the net weight display

automatically after a tare weight has been set, and the

indicator will switch to the gross weight display after the

tare weight has been reset.

─ 4-1 ─

F02 : Weight Unit

F02 allows you to select the unit of weight.

F03 : Display Frequency

The display update rate of the indicator can be selected by

the user via F03. For examlpe, if the display frequency set to

"0:16 times/sec.", then the indicator will display the weight

per 8 times A/D conversion.

F04 : Power-On Auto Zero

The indicator will zero the display once at the electric power

is connected, if the "Power-ON Auto Zero" function is valid.

The user can select the "Power-ON Auto Zero" function to be

valid or inhibited via F04.

F05 : Zero Tracking

If there is a small deviation, beyond the zero point, within a

set range and this state continues for more than a set period,

the "Zero Tracking" function will bring the display back to

zero automatically. The indicator needs the user to select a

zero tracking range and a zero tracking period via F05 to

to perform the zero tracking.

F06,F07 : Digital Filter I and II

The indicator is designed to use the double stage digital

filters to reduce fluctuation of a weight value. The 1st stage

digital filter selector can be selected from "0" to "4" via

F06 and the 2nd stage digital filter selector can be selected

from "0" to "2" via F07. The display will be more stable if

the number of the filter selector increases, but the response

will be worse instead. To the contrary, if the number of the

filter selector is reduced, the response becomes better

although the display may not be stable. Select the best number

according to the measurement.

F08 : Stable Detection

The indicator needs the user to select a stable range and a

stable period via F08 to perform the stable detection. The

─ 4-2 ─

stable range is denoted by the minimum scale division and the

stable period is denoted by the time in seconds. The indicator

will be easier to enter the stable state if a larger stable

range and a shorter stable period is selected, although the

display may be fluctuant.

４.３ Adjustment & Calibration (F50～F58)

Ｙ our indicator should be calibrated when first installed, or

after a weighing system component (load cell, A/D circuit board, ...

.. etc.) has been changed. All weighing systems should be calibrated

at least once every 12 months. Please allow a warm up (plugged in)

for at least 30 minutes to achieve thermal stability before starting

calibration. For best accuracy, calibrate with as near to full span

weight as possible.

Full Calibration Procedure :

Step 1 : Open the "CAL Switch" cover on the rear panel and slide the

────

"CAL Switch" on. F50～F59, F60 and F61 will not CAL SW

be executed if the "CAL Switch" is at the off

position. An error message〔E r C A L S 〕will OFF ■ ON

be displayed, if any one of these functions has

been selected without setting the "CAL Switch" on.

Step 2 : Set the parameter for the Zero Range via F50.

────

The indicator allows the user to press the [ZERO] key to return

the display to the center of zero when the weighing device is

empty. This function works only if the offset value is within a

set percentage limit, which is called "the Zero Range", of the

weighing device full capacity. An error message〔E r r o r 0 〕

will be displayed, if an offset value is beyond the zero range and

a zero operation has been proceeded.

Step 3 : Set the decimal point place via F51

────

The decimal point place of the display weight value can be set via

─ 4-3 ─

F51. The default for the decimal point place is "1 : X X X X X.X".

Step 4 : Set the "Minimum Division" via F52.

────

The "Minimum Division" can be set to 1, 2, 5, 10, 20 or 50.

Step 5 : Set the "Maximum Capacity" via F53.

────

The "Maximum Capacity" is the full weight that you want your

weighing device to handle. It could be the rated capacity of the

loadcells, or some other limit you wish to be. The maximum

capacity also has a relationship to the display resolution. In

general, the display resolution of an indicator has the form of a

ratio of the maximum capacity to the minimum division. The disaply

resolution of this indicator can be from 300 to 30000. Thus,

300 ≦ [(the Maximum Capacity) / (the Minimum Division)] ≦ 30000

The following messages may be displayed as an error indication

during the maximum capacity setting:

〔E r F 5 3 1 〕: The maximum capacity is not a multiple of the

minimum division.

〔E r F 5 3 2 〕: The resolution is under 300.

〔E r F 5 3 3 〕: The resolution is over 30000.

Step 6 : Proceed the "Zero Adjustment" via F54.

────

The "Zero Adjustment" is a process to give the HB8215/6 a base

reference point "ZERO", to the weighing device when it has no

weight on it.

<1>. Select F54 Function:

Display → C A L - P O

○ ○ ○ ○ ● ●

<2>. Make sure that there is no weight on the weigher and the

weigher is stable (●STAB lights ON),then press the [ENTER]

key.

Display → C A L - P O

○ ○ ○ ○ ● ●


<3>. If the input signal from the loadcell is ok, the HB8215/6

will display [End-P0] message for two seconds and the zero

adjustment will be done.

Display → E n d - P 0

○ ○ ○ ○ ○ ●


<4>. Error Messages :

〔C A L E r 1 〕: The input signal from the loadcell is

unstable.

〔C A L E r 2 〕: The HB8215/6 is not able to achieve zero

adjustment because of the input signal from

the loadcell is under 0.1mV or negative.

〔C A L E r 3 〕: The HB8215/6 is not able to achieve zero

adjustment because of the input signal

form the loadcell is too large.(over 25mV)

Step 7 : Proceed the "Span Pt.n Calibration" via F55,F56,F57,F58.

────

The "Span Calibration" allows you to set 4 reference points (P1,

P2,P3,P4) between the empty point (P0) and the end point (Maximum

Capacity) of your weighing device that will give the HB8215/6 an

algebraic difference of each digital increment (Division). With

the Span Calibration, the HB8215/6 can accurately calculate what

weight is on the weighing device.

by over 1000 divisions.(n = 2,3 or 4) That is,

(Point n) ＞ (Point n-1) + 1000 divisions

Rule 2 : The nonlinearity between the calibrated points

should be smaller than 0.2%. That is,

SPAN(Ｐ nＰ n-1) － SPAN(Ｐ 1Ｐ 0)
