INSTALLATION & PRECAUTIONS
Environment
The weighing indicator should always be used in an environment which is free
from corrosives and temperature/humidity extremes. These factors will affect
displayed weight readings.
Before starting the operation of the indicator, please read the following
instructions and operate the scale properly.
DO NOT (install the indicator):
●next to doors causing rapid temperature changes or under direct sunshine.
●near magnetic fields or equipment that generates magnetic fields.
●either expose the indicator to water or place in humid place. It may cause
damages on the unit.
●either remove the display housing or separate the inside parts. It may cause
troubles on the indicator.
●apply strong solvent such as benzene and thinner for cleaning indicator.
It may affect on the plastic material.
Always:
●operate the indicator within the temperate range from-5 ˚C to+40 ˚C.
operations out of this range may obtain inaccurate weight readings.
●use soft cloth with or without neutral detergent for cleaning.
●use the rated power supply 110-120VAC or 220-240VAC as indicated on the
right-hand side of the display to operate indicator or charge battery (6V/4Ah).
●use an AC power regulator to stabilize the power supply if the local electricity
supply fluctuates by more than ± 10%
Grounding the indicator and connecting the LOADCELL
A green wire with a terminal enclosed in the battery compartment is used for
grounding purpose.
Please connect the indicator with load cell as the following Indication.
※ It could be dangerous by using improper battery or wrong connection of
battery.

TURN ON THE INDICATOR
Indicator will show the whole LCD with backlight and then start to count down
from 9 to 0 and then will display the software version.
Finally. the display will be stable at zero position and ready for use.
BATTERY STATUS INDICATION
This unit can operate continuously by connecting directly to AC power or 100
hours by fully-charged rechargeable lead-acid battery.
The operation time will be approximately half of the above mentioned time
span if the backlight is always effective after the indicator is turned on.
When battery voltage is low. a battery sign will start blinking to remind users to
recharge the battery. Unit will be automatically turned off about 8 hours after
the battery sign starts blinking in order to avoid inaccurate measurement or
calculation. Unit can operate properly before power is automatically turned off.
RECHARGING BATTERY
Recharging battery when the battery sign starts blinking. When battery is
being charged, the LED indicated by the word CHARGE on the right-hand side
of the display panel will be RED, the LED will become GREEN when the
indicator has been charged to full capacity (charging time is about 8 hours).

RELATION BETWEEN LOAD CELL OUTPUT AND
INPUT SENSITIVITY
The input sensitivity is 0.6μV/D or more. The input sensitivity indicates the
variation in the load cell output voltage required to change the display one
point on the display. When designing a weighing system, the load cell output
voltage must satisfy the input sensitivity of the JWI-586. For this purpose, the
system should be designed so that the following equations are satisfied. In
order to achieve a system with stable performance, it should be designed so
that sensitivity is as great as possible.
A：Load cell rated load
B：Load cell rated output [ mV / V ]
D：Minimum division
（5000 is the excitation voltage in millivolts）（5V）
（0.6 is the input sensitivity in µV）

Example：To make a weighing system wi t h a maximum capacity of 300kg and
minimum division of 0.05kg, using a single load cell with ratings of
500kg and 3mV/V. In this example, A＝500, B＝3 and D＝0.05, so
that the right-hand side of equation a is as follows：
5.1

05.035000 = ××

There is thus no problem with the design.
If multiple load cells are used, the design should ensure that the following
