SAFETY PRECAUTIONS
All safety messages are identified by the following the words “WARNING” and “CAUTION”. These words mean the following:
WARNING: Important information to alert you to a situation that might cause serious injury and damage to your property if instructions are not followed.
CAUTION: Important information that tells how to prevent damage to equipment.
When using the scale/balance, the following safety precautions should always
be followed.
WARNING: Use only the AC adaptor with the scale/balance. Other adaptor
may cause damage. (AC adaptor is optional)
CAUTION: Avoid installing the scale/balance in direct sunlight; this may
cause discoloration or malfunctions. Do not mix the type of batteries. Replace
all other batteries at the same time. If the scale/balance is not to be used
for a long period of time, remove all batteries from the battery compartment
to avoid leakage which may cause damage to the instrument. Avoid overloading
that could cause damage to the scale/balance. Do not drop water in the
scale/balance that is not water-resistant. It causes damage, if inside of the
scale/balance is wet. Matter charged static electricity could influence the
weighing. Discharge the static electricity. As example, the method is to use
the electrification prevention spray, to spray it to both side of weighing
platform.

Setting up the scale/balance
CAUTION!
Avoid installing the scale/balance in direct sunlight that may cause
discoloration or malfunctions. Place your scale/balance on a firm weighing
table so that the scale/balance is level. (The scale/balance will not perform
accurately when it is not level.)
Place the scale/balance on the firm surface that is flat and level for an
accurate weighing.
- Selection of auto backlight mode: When the balance enter function setting menu. Press [UNIT] key, the display will show L_ON or L_OFF, press [ZERO], selection display L_ON, this means auto backlight function active, press [ZERO] again, the display will show L_OFF, this means auto backlight function inactive, i.e. shut off backlight function.
- Selection of auto shut off mode: When the balance enter function setting menu. Press [UNIT] key, the display will show A_ON or A_OFF, press [ZERO], selection display A_ON, this means auto shut off function active. Press [ZERO] again, the display will show A_OFF, this means auto shut off function inactive.
- Return to weighing mode: Press [ON/OFF] to turn the power off, press [ON/OFF] again to turn on the power and the scale return to the weighing mode.
Counting procedures
-
Press [ON/OFF] to turn on the scale: Wait for “0” to appear on the display.
-
Start the Count Procedure: If necessary, press [ZERO] key to set the display to “0”.
-
Place a given number of samples of an item on the pan (the Sample Size should be either 10 20 50 or 100 pieces). The weight of these samples will show on the display.
-
Press the [PCS] key several times to put the scale in PCS mode.
-
Select the sample size (the same as you chose above) by pressing the [PCS] key. (press it as many times as necessary to put it in the correct sample size ,the sample size is the same as in step three =10 20 50or100.
-
Press the [UNIT] key, the display will show “selected pcs”, then the scale will remember the sample size you selected and show the starting sample size on the display
(you can now remove the samples if you want to return the scale to 0) -
Place the items that you want counted onto the tray and the total number of items will show on the display.
-
Presses the “PCS” key to exit the counting function and return to normal weighing or you can press ON/OFF to turn the scale off to exit .
NOTE: the weight of unit sample > 10e.
WEIGHING
Before weighing
Whenever possible, please allow the balance to warm up for 10 minutes after
first turning to power on, so that the balance will function. Properly and
accurately.
Error messages
EEEE: Overload : Low battery
Calibration may be required before weighing.
Read “CALIBRATION” first and if necessary, calibrate your scale/balance for
accurate weighing.
Weighing procedures
- Press [ON/OFF] to turn on the scale/balance: When power is turned on, all display segments appear on LCD for a few seconds and finally “0” will appear on the display.
- Select the weighing unit with [UNIT]: Press [UNIT] to select a weighing unit, eg. “g” ” ct ” ” oz “˜” dwt “˜”ozt”˜”gn”˜”lb”˜”n”. Once the unit has been selected, the selected unit will be displayed to the weight value.
- Start weighing:
- If you do not use a container for weighing: Verify the reading is “0”. If not, press [ZERO] to display “0”. Place objects on the weighing platform to weigh. When the reading becomes stable, the stable indicator is displayed.
- If you use a container for weighing: Place an empty container on the platform. Wait for the stability indicator to be displayed and press [ZERO]. Place the objects to be weighed in the container. When the reading becomes stable, the stable indicator is displayed.
CALIBRATION
When to calibrate
When first installing the balance, the factory will still be valid, of course. However, if it is exposed to severe environmental conditions such as dust, contamination, high humidity, a re-calibration can be mades. The common calibration intervals should also be adhered to (e.g. annual re-calibration according to ISO).
How to calibrate
- The scale must be turned off.
- Press and hold the [Unit] key and at the same time press the [ON/OFF] key. The scale will now enter calibration mode and display a random number such as 0247581811, which is tha indication of A/D converter (the signal of the weighing sell). When loading the scale, this number should increase and when removing the load, it should decrease and stabilise. Now press [UNIT] key to confirm the zero point. The weighing platform should be free from any load. The display will show “00SAVE” for a short time and go to the first calibration point “2000.0” (PCE-BS 3000) or “200.00” (PCE-BS 300). Now load the scale with the 2000 g weight. Then press the [Unit] key again. The display will show “00SAVE” again and then go to the second calibration point “3000.0”. You can either cancel the calibration by pressing the [ON/OFF] key or load the scale with a 3000 g weight and press the [Unit] key again. “00SAVE” will be displayed for a short time. The two-point calibration is now completed and the display will again show the signal of the A/D converter. With a PCE-BS 300, only a single-point calibration (200 g) is possible!
- Turn off the balance and turn it back on by pressing the [ON/OFF] key. Carry out a few weighings. In case you believe there are still some deviations, repeat the calibration procedure. If you prefere so, you can also contact PCE nstruments for professional calibration at the calibration laboratory. The calibration is complete.
