First use of the balance

Open the package carefully and keep the packaging for possible later shipment of the balance. Place the weighing plate on the balance and connect the mains adaptor.
Set-up site

Keep the set-up site clean and dry.
Place the balance on a flat and stable surface.
Avoid draughts and temperature fluctuations, e. g. through open windows and doors, installation under heaters or in direct sunlight.
Avoid the effect of vibration on the balance.
Make sure that the balance is not influenced by other devices.
Static charge may occur in dry environments.
Keep the balance away from objects with magnets and from magnetic fields.
Do not use the balance in areas where there is a risk of explosion.

To align the level horizontally, you can adjust the feet. The bubble of the spirit level should be exactly in the circle marked in red. When the balance is started, the display shows the following, one after the other:

F5 – 7.1 – Current program version number
C – 03- Weighing range in kg
dC – 6.6 – Current-voltage (CE-Err means the mains adaptor is connected)
0,0 – Current weight on the weighing platform
o – Power-saving mode (after 1 minute without load) / Press any key to return to weighing mode.

Setting the filter of the digital display
If you press “MODE” and “-> T<-” in weighing mode, you can switch between three speeds (F … high, M … medium, L … low). Pressing the key combination several times switches between the setting options.

Function settings

Press the “On/Off” key and then hold down the MODE key until “F—1” appears on the display. Press MODE to go to the basic settings, press >0< to go to F—2, F—3, F—4, etc.

| Function| Description
---|---|---
F—1| Basic settings| Continue to C03 with MODE, to F—2 with >0<
C-03| Weighing range| 1.5 / 3.0 / 6.0 / 7.5 / 15 / 30 in kg

Select value with >T<, continue with MODE

Select with >T<, continue with MODE

br-3| Display brightness| 0 / 1 / 2 / 3 select with >T<, continue with MODE

(br-0 stands for the highest brightness)

PS-01| Power saving mode| PS-00 – no power saving PS-01 – power saving

PS-02 – rear display off – select with >T<

---|---|---
E–01| Sensitivity| 00 / 01 / 02 / 03 / 04 / 05 / 06 / 07 / 08
P-OFF| Activate weight limits| Select P-OFF / P-ON with >T<, continue with MODE

Under F—6, the values can be set.

When weighing, the following glows on the left below the display:

– Down (red) – if value is below lower limit value

– Pass (green) – if value is within specified range

– Up (red) – if value is above upper limit value

t0-OFF| Zero tracking| Automatically corrects deviations of the zero display

– t0-OFF / t0-ON – select with >T< (should always remain activated)

F—2| Single-point calibration (We recommend using at least 2/3 of the max. load -PCE-BSW 3 – 2 kg

and PCE-BSW 7 – 5 kg )

| When “LOAD” is displayed, place the weight on the weighing plate. Confirm with MODE. When “L0000.0” is displayed, enter weight with >0< and

T<. Confirm with MODE. A double dash line appears, then the measured value and the

calibration is finished.

F—3| Dual range balance

!! not available !!

| “FUNC-1″/”FUNC-2” Dual range not available!!!

T< to change, MODE to continue to F—4

F—4| AD converter| Display for checking the function of the load cell

The numerical value must increase when the balance is loaded and decrease when the load is removed.

F—5| Three-point calibration (The required weights depend on the weighing range of the balance ).| “CAL”, then “ 3000 ” -> put on 3000 g Double line, then “ 3000 ” -> remove weight Double line, then “ 2000 ” -> load 2000 g. Double line, then “ 2000 ” -> remove weight Double line, then “ 1000 ” -> load 1000 g Double line, then “ 1000 ” -> remove weight

Double line, then “0.0” -> calibration is finished

F—6| Set weight limits (for activation, see “P – OFF “)| Change position with >T<, change value with >0<, confirm entries with MODE,

“L0000.0” lower, “H0000.0” upper limit value

-END-| End of settings menu| Balance automatically goes to weighing mode

Attention!
The greyed-out menu items should not be used without consulting a service technician. Be sure to follow the instructions on the following page!

Notes on changing the function settings

General If you change default settings, check the display values afterwards with a known weight. If there are deviations, recalibrate/adjust the balance. To do this, call up single-point (F—2) or three-point calibration (F—5) in the function menu. For the one-point calibration you can select the weight yourself. For three-point calibration, fixed weights are required. During calibration, the balance is automatically adjusted to the respective weights and ambient conditions.
Changing the weighing range (Should not be done by the customer!) After each change of the weighing range, the balance should be adjusted (see item 1). Please do not change the weighing range as the load cells are not designed for this.
Changing readability/resolution (Should not be done by the customer!) The possible settings are 01 / 02 / 05 / 10.
Changing decimal places (Should not be done by the customer!) You can set 0, 1 or 3 decimal places. It is possible to set values here that do not match the other settings (e. g. three decimal places for the unit gramme, no decimal places for the unit kilogramme). After changing the decimal places, check with a known weight whether the balance displays correctly. Otherwise, you must adjust the balance (see item 1).
Changing the weight units You can select grammes (g), kilogrammes (kg), pounds (lb) and carats (CT). If one of the first three units is selected, the respective indicator on the right below the display glows.
After changing the weight unit, check with a known weight whether the balances displays correctly. Otherwise, you must adjust the balance (see item 1). When kg is set, the decimal place changes with it. This must be adjusted again when changing to grammes.
Changing the sensitivity Here, you can set how sensitively the balance reacts at very low loads. For example, if you set the sensitivity to E-03, the balance will only display from 0.3 g when the resolution is 0.1 g and from 3 g when the resolution is 1 g. If you want the balance to display even the smallest quantities, set the sensitivity to E-01.
Limit value function – P-OFF/ P-ON Here, you can activate that a visual indication appears on the left below the display if upper or lower weight limits are not met. If the function is activated, you can set the weight limits within the weighing range under F—6.
Zero tracking With automatic zero tracking, very small quantities are not added up but ignored in order to stabilise the zero point. This “zeroing” of very small quantities can cause undesired false readings in so cases Instrument

Charging the battery
If the battery voltage is low, the light next to “UnderVoltage” on the left of the display glows. Connect the mains adaptor and charge the battery. The connector is located at the bottom of the housing, in the recess in front of the front right foot of the balance. During charging, the light next to “InCharge” to the left of the display glows.

Troubleshooting

Problem	Possible cause	Solution
No display	Low or no voltage	> Recharge batteries in time

Check whether charging via the mains adaptor works

Weight display not stable| – Influence by the environment (vibration,

temperature fluctuations),

– Objects between weighing plate and housing

– The weighing material is not stable

| > Keep the environmental conditions as stable as possible

Remove objects

Fix the weighing product

Weighing is not correct| – No calibration

– No taring before weighing net weights

– Readability, decimal places, unit set incorrectly

– With very small values, the display remains 0 if the “E-0” value is too high or automatic zero tracking has

been activated

| > Calibrate and -if necessary- adjust

Tare before weighing

Check the set values

For small quantities, make sure that E-01 and t0-OFF have not been changed

“CE-Err”| Scale displays

“CE-Err” when switched on

| > Reconnect the mains adaptor to charge the battery
“-Err-“| – Quick calibration with wrong weight

– Upper limit value outside the weighing range of the balance

| > Use suitable calibration weight

Adjust limit value

„- – – – – -“| Weight of the item to be weighed exceeds the weighing range.| Only load up to the specified max. weight
