1. INSTALLATION
1.1Select the Location
Avoid heat sources, rapid temperature changes, air current or excessive vibrations. Allow sufficient space.
1.2 Leveling
Be sure the balance is level before it is used or after its location is changed. The PJX balance has a level bubble
in a small round window beside the display. To level the balance, adjust the 4 leveling feet until the bubble is
centered in the circle.
Please refer to the below figure for leveling.

1.3 Connecting Power and Acclimating the Balance
Connect the DC output connector to the power receptacle on the rear of the balance. Then connect the AC adapter
plug to a suitable electrical outlet.
Acclimating
It is suggested that the balance should not be used until it has been acclimated to the environment for a certain
period of time. In the case of a balance with the precision above 0.1 mg, the pre-acclimation time should be 1.5
hours; in the case of a balance with the precision of 1 mg, the acclimation time should be more than 0.5 hours.

2.2 Initial Calibration
For best results, the instrument's calibration should be checked prior to first use. If adjustment is needed, refer to
the Calibration section of the instruction manual.
Steps for calibration
1. Press and hold the Tare / Menu-Cal button, and the
Calibration Menu will display.
2. Press Yes to enter the Calibration Menu.
3. To change the calibration mode, press No until SpaN
(span calibration) is displayed.
4. The Calibration mass value will be shown in the screen.
After the display shows 200.0000 g, place weight(s) of
200 g on the pan for calibration. To change to the
calibration point of half full capacity (e.g. 100 g), press
the Function / Mode button. After the screen shows
"Place weights" and "100.0000 g", place weight(s) of
100 g on the pan for calibration.
5. Once the span calibration is completed successfully,
CAL.Done will display.
Press any button to return to the previous screen.
6. Remove the weight(s), and the reading will be set to
zero.

3. CONNECTING THE INTERFACE
The PJX balance has two connectivities, RS232 port and Mini DIN.
Use the RS-232 port to connect either to a computer or a printer with a standard (straight-through) serial cable.
Mini DIN is used to connect with another accessory, as an alternative option for RS232.

4. MAINTENANCE
4.1 Cleaning
Please disconnect the balance from the power supply before cleaning. Make sure that no
liquid enters the interior of the balance.
Clean the balance at regular intervals. Housing surfaces may be cleaned with a lint-free cloth slightly dampened
with water or a mild cleaning agent. Glass surfaces may be cleaned with a commercial glass cleaner.
Attention: Do not use solvents, harsh chemicals, ammonia or abrasive cleaning agents.
4.2 Troubleshooting
Symptom / Display
Possible Cause
Err 8.1
Weight reading exceeds Power On Zero limit.
Err 8.2
Weight reading below Power On Zero limit.
Err 8.3
Weight reading exceeds overload limit.
Err 8.4
Weight reading below underload limit.
Ref Err
Reference Weight too small. The weight on the pan is too small to define a valid
reference weight. Add additional samples.
LowW.rEF
A warning that the reference weight is below the recommended value for accurate
parts counting. Add additional samples if possible otherwise counting continues
with diminished accuracy.
