INSTALLATION
1Unpacking:
Unpack the scale. Save the packing container for future use.
2Electrical requirements:
The scale requires very stable power. It works on 230V AC supply with PROPER EARTHING. The
power outlet used for the scale should not be shared with any other devices which draws current in
inconsistent manner like Airconditioner or refrigerator etc. Scales supplied with optional inbuilt
battery backup
3 Environmental requirements:
For best results, the scale should be placed on a level surface which is free from drafts. It should not
be exposed to direct sunlight or radiated heat. The scale should not be subjected to sudden ambient
temperature changes. Table used for scale should be sturdy and should not transmit vibration from
other equipments and free from the movement of people. No vibration producing equipment should
be operated on the same platform as scale.
4 Start up.
Power is supplied to the scale through a 2 pin dc adaptor supplied along with the scale. Connect the
adaptor to the scale to dc jack provided at the side of the scale. Connect the adaptor to an AC mains
outlet with proper earthing.
Scale goes through the self test and subsequently starts displaying weight
Press key to zero the weight, if required.
COUNTING SCALE KEYBOARD AND DISPLAY
SWITCHING BETWEEN ITEMS.
Scales have a memory of 500. Unit weights of 500 items can be stored in memory. Scales retain the
unit weight value even when it is switched off.
To switch between different items, Press item memory number and press to select.
For example to select memory no. 125,
Press and
SETTING UNIT WEIGHT THROUGH KEYBOARD
Unit weight can be either set through the keyboard or scale calculates it with known number of
samples.
For Unit weight entry, Press , Scale displays
Unit wt display indicates the current unit weight and pieces display indicates the memory no.
Use numeric keys to enter new unit weight. Press key to store new unit weight.
Press to quit without saving.
SETTING UNIT WEIGHT WITH KNOWN NO. OF SAMPLES
Scale calculates unit weight when known number of samples are on the pan.
Remove all items from the pan and make weight reading zero by pressing key.
Keep container on the pan , if required, and Press or key to zero the weight.
Put known number of samples on the pan.
Press key. Scale displays
Enter no of samples on the pan using numeric key pad.
Press key. Scale calculates the Unit Weight and displays on the Unit Wt. Display.
AUTOMATIC COUNT CALIBRATION MODE. (ACCM)
Scale is equipped with a facility to calculate unit weight by averaging over large number of samples
without actually counting large quantities manually.
Put known number of samples on the pan.
Press key. Scale displays
Press key again. Scale displays
Now scale is in automatic count calibration mode.
Enter no of samples on the pan using numeric key pad.
Press key. Scale calculates the Unit Weight and displays on the Unit Wt.
Display.
When scale is in ACCM mode, the piece nos display will be blinking.
Add more sample to the existing no to make number of pieces double the original quantity.
Wait for the weight to become stable. Scale recalculates the unit weight and displays on the Unit
weight display.
Repeat this procedure till desired number of samples are averaged.
Press key to quit ACCM mode.
HOLD FUNCTION
Weighing and counting can be held temporarily by using HOLD function.
Keep the key pressed for more than 3 sec. Scale will display
Press key to quit this mode.
GROSS/NET FUNCTION
Press key to switch between GROSS and NET weight function. To use this function,
Remove all items from the pan and make weight reading zero by pressing key.
Keep container on the pan , if required, and Press key to zero the weight.
Keep sample on the pan.
Press to switch between GROSS and NET weight mode.
When key is pressed. Scale returns to NET weight mode and container/tare weight will be
made zero ,
TARE/CONTAINER WEIGHT ENTRY
Tare or container weight can be entered directly, if, it is known to the user.
Keep a container with samples on the pan of the scale. It displays say,
Press key. Scale will display
Current container/tare weight will be displayed in the Unit Wt. Display area.
Press key to store Tare weight.
Scale enters NET weight mode, subtracts Container weight from the total weight and displays.
MEMORY FUNCTION ( M+ and MR)
No. of Pieces counted can be added to its respective memory and can be retrieved if required. For
eg.
Press key. Quantity 2114 will added to the memory , say memory 1
Press key again. Quantity 2114 will added to the memory 1
To Retrieve the accumulated total, Press key. It displays
For Clearing memory, , Press key. It displays
