2.2 External Connections
2.2.1 Battery Power Supply
The indicator comes with one lead-acid battery installed by factory default.
Note: The lead-acid battery will charge automatically while connecting to the power supply. When charging, the
battery level indicator increases or decreases in one grid, two grids, three grids and four grids. The battery level
indicator will disappear when the battery is fully charged.
While operating on battery, the battery symbol indicates the battery status:
Battery 5%~25% remaining
Battery 25%~50% remaining
Battery 50%~75% remaining
Battery 75%~100% remaining
Attention: Before using the indicator for the first time, the internal rechargeable battery should be
fully charged for up to 12 hours. The indicator can be operated during the charging process. The
battery is protected against overcharging and the indicator can remain connected to the AC power
line.
CAUTION: BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED B-TEK SERVICE
DEALER. RISK OF EXPLOSION CAN OCCUR IF THE RECHARGEABLE BATTERY IS
REPLACED WITH THE WRONG TYPE OR IF IT IS NOT PROPERLY CONNECTED. DISPOSE
OF THE RECHARGEABLE BATTERY ACCORDING TO LOCAL LAWS AND REGULATIONS.
Dispose of the lead acid battery according to local laws and regulations.
2.2.2 AC Power Supply
Connect the AC plug to an electrical outlet to power on the indicator. Connect the other end to the indicator if
not connected.

T104 Series Indicators EN-13
2.3.2.3 Load Cell Terminal Block Connection
Proceed with the previous section, to connect the load cell terminal block, first locate it on the mainboard
following the instruction in the previous two sections for the two models.
After finding the load cell terminal block, check Table 2-1 for the definition of each terminal screw connection
and make connections based on it. Please note that when using four-wire load cells, jumpers (the two short
wires supplied) must be placed between the +Excitation (+EXE) and +Sense (+SEN) terminals and between
the -Excitation (-EXE) and -Sense (-SEN) terminals.
The T104P and T104S indicators are designed to support both 2mV/V and 3mV/V load cells from the same
circuitry. A load cell output rating selection jumper is not required.
2.3.2.4 Load Cell Connection
After finding the load cell connector, check Table 2-2 for the definition of each pin.

Note: Short press the Function button can display the over and under value.
3.4.2 Positive Check
Positive check is used to determine when the material added to the scale is within the target weight range. In
this case the under and over values must be positive values. (The over value must be greater than the under
value.)
To start, add material to the scale pan until the display turns green.
3.4.3 Negative Check
Negative check is used to determine when the material removed from the scale is within the target weight
range. In this case the under and over values are both negative values. The under value must be greater than
the over value. (For example: the under value is -10; the over value is -15).
To start, place a package or bin of material on the scale and press the Tare button.
Remove a portion of the package or material until the display turns green.
To continue weighing multiple portions off the scale's pan, tare the scale between each portion.
3.4.4 Zero Check
Zero check is used when comparing subsequent samples to an initial reference sample. In this case, the under
value must be zero or a negative value and the over value must be zero or a positive one.
Place the reference sample on the scale and press the Tare button.
Remove material from the scale pan until the display turns green.
