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.

〔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.

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)
