PRECAUTIONS BEFORE USING THE BALANCE
For safe and dependable operation of this balance, please comply with the
following safety precautions:
• Verify that the input voltage printed on the AC Adapter and the plug type
matches the local AC power supply.
• Make sure that the power cord does not pose a potential obstacle or
tripping hazard.
• Disconnect the scale from the power supply when cleaning the scale.
• Do not operate the scale in hazardous or unstable environments.
• Do not immerse the scale in water or other liquids.
• Do not drop loads on the platform.
• Use only approved accessories and peripherals, as available.
• Operate the scale only under ambient conditions specified in these
instructions.
• Service should be performed by authorized personnel only.
• It must not be bumped against by other items or overloaded with
excessively heavy weights (The load must not exceed the maximum
capacity of the balance).
• Give a warm-up for 30 mins before using the scale.

NAME AND TYPE OF THE INSTRUMENT
The HT-NA model weighing balance is a self-indicating weighing scale of
Class II with single weighing range, an external AC mains adapter, and an
internal rechargeable battery.
The balance consists of analogue to digital conversion, microprocessor
control, power supply, keyboard, and a weight display contained within a
single enclosure.
KEYS AND DISPLAY DESCRIPTION
The balance is equipped with 13 keys membrane keypad to control the
functions and also the ON/OFF of the balance.

Keys function
ON/OFF switch.
Function key to choose weighing, parts counting and percentage
weighing.

Display
When the Capacity of the balance is 600.0g, the last digit will be the auxiliary
display digit (a symbol indicating the digit):
When the Capacity of the balance is 150.00g, 300.00, 1500.0 and 3000.0g, the
last digit will be blank in normal weighing mode only if the key is pressed
to extend the display.
FUNCTION
The balance can be available for operation from mains at 110~240V (50/60Hz)
with an external AC/DC adapter with 12V output voltage and an optional
internal 6V rechargeable battery.
11
POWER-UP
When power up the balance, the display will first show the software version
(Ver. 1.00) for 2 seconds and then perform a self display test. Then it will
show the Calibration counting times for about 1 second. After that it will
automatically establish the current weight as a new zero reference point.
WEIGHING MODE
Display range
The display can show weight from –Max (Tare weight) to Max+9e (Gross
weight).
Zero-Setting
Zero-setting range: ±2% of Max
Zero-setting is only available when the load receptor is not in motion (The
display is stable).
Semi-automatic zero-setting
When there is a minor weight displayed (without load on the pan), press
key to return to the display to zero, then the Zero symbol appears which
indicates that the display now is at the zero point.
Zero-tracking
The instrument is equipped with a zero-tracking feature which operates at a
12
speed of ±0.25e/s and only when the indicator is at gross zero and there is no
motion in the weight display.
Initial zero-setting
Initial zero-setting range: ±10% of Max
When the initial zero-setting range is below -10% of Max, the display shows
“-------” and the buzzer sounds. To return the display to normal mode,
please adding more weights until the initial zero-setting range is between
±10% of Max.
When the initial zero-setting range is beyond +10% of Max, the display shows
“-------” and the buzzer sounds. To return the display to normal mode, please
take off weights until the initial zero-setting range is between ±10% of Max.
Tare
The instrument is provided with a semi-automatic subtractive tare.
Semi-automatic tare

appears and the display will show a net weight of the object to be weighted.
key to subtract the current displayed weight value as the tare

To clear the tare value, please remove the container on the pan, then the
display will show a minus tare weight value and press
Note:
1. When performing the tare operation(s), make sure the instrument is in stable.
2. If consecutive tare operations have been performed, to clear the tare value,
please remove all the containers on the pan first and then press

key.
Units selection
Press the key to choose the weighing units and the display will be
changed to the new value with the units shown. There are up to 8 units of
weight that can be enabled.
Overload alarm
When the weight on the pan exceeds the Max. capacity, the display will show
“--OL--” at the same time the buzzer sound. Please take off the weight at
once. Otherwise the load cell will be easy to be damaged.
Counting mode
In normal weighing mode, press the
mode. The display shows as below:

Press
key or key to choose the sample size (10, 20, 50, 100, 200,
500 and 1000 pcs).
After a desired sample size has been chosen, put the samples as the chosen
sample size on the pan and press the
key. Then the “Mode” symbol
starts flashing and the “C” disappears.
Then the sampling procedure is finished. And the balance can be used for
parts counting.
Note: If the unit weight is two small (less than 0.2 scale division), the display
will show “- -or- -pcs”.
Percentage weighing mode
In normal weighing mode, press
weighing mode.
key twice to enter into percentage
15
Press
key or key to switch between 100.0% or 100.00%.
Put the sample considered to be 100% on the pan, and then press the
key
to perform sampling process. Then the “Mode” symbol starts flashing and
several seconds later, the “Mode” symbol and “P” disappears.
Then the sampling procedure is finished. Take away the sample and put
other objects on, the display will show a percentage (the objects’ weight to
the 100% sample weight).
• The sample weight considered to be 100% should be larger than 0.2d,
or the display will show “- -or- -%”, which indicates that larger sample
weight should be put on.
Note:
1. Press the
key after the sampling procedure (parts counting or
percentage weighing) is finished, it will return to normal weighing mode.
Then press the
key, the balance will return to parts counting or
percentage weighing mode again; and the sampling data can also be used.
2. The sampling data will be cleared automatically when after switching
between counting mode and percentage weighing mode.
