POWER CONNECTIONS
Power Supply
To power the 750 indicator without batteries, connect the 12 VDC, 1 Amp power supply’s
connector into the power jack on the back of the indicator and then plug the power supply into
the proper electrical outlet. See Figure 1. On models requiring 220 VAC, it is the customer’s
responsibility to obtain the correct power adapter plug. The 750 is now ready for operation.
NOTE! The power supply is also used to recharge the batteries, when
the indicator is operated from Ni-Cad or NiMH batteries.
Batteries
Battery operation is a standard feature of the 750 indicator, although the batteries are optional
(not included). The indicator can be operated from 6 "AA" size Alkaline, Ni-Cad or NiMH
batteries. You must first obtain and install batteries before operations can begin. Batteries are
contained in a battery holder inside the indicator. Access is via a removable panel on the back
of the indicator.
When using batteries, all 6 batteries must be of the same type. They must be all Alkaline, Ni-
Cad or all NiMH. In addition, DO NOT mix Ni-Cad or NiMH batteries.
CAUTION! The 750 indicator has internal circuitry that when used in conjunction with
the external power supply, recharges the Ni-Cad or NiMH batteries. Because the
indicator has this charging capability, DO NOT connect a power supply to the
indicator if using Alkaline batteries.
Battery Operation
The 750 indicator will operate for up to 250 hours on new Alkaline batteries or for up to 100
hours on fully charged Ni-Cad or NiMH batteries depending on the condition of the batteries
(from new to about 500 recharges). The battery bar graph on the display indicates the battery
capacity in 4 steps:
4 segments - the full battery capacity is available,
3 segments - the battery is at 75% of capacity,
2 segments - the battery is at 50% of capacity,
1 segment: - the battery is at 25% capacity.
When the battery voltage drops too low for accurate weighing, the indicator will show "7<
and then shut off. You will be unable to turn the indicator back on until the Alkaline batteries
have been replaced or the AC power supply is connected to the display to operate it and
recharge the Ni-Cad or NiMH batteries.
Battery Charging
To recharge the Ni-Cad or NiMH batteries, the AC power supply must be connected to a power
outlet and plugged into the indicator. It will take approximately 8 to 10 hours to fully recharge
the batteries in the display. Charging the batteries for more than 10 hours will not damage
them. NOTE! The indicator may be operated while the batteries are charging.

KEYPAD FUNCTIONS, CONT.
This key is used to reset the display to zero up to the selected limit of either 4%
or 100% of scale capacity. The zero limit is set during setup and calibration of
the indicator.
This key is used to change the weighing units to the alternate units of
measurement. For example, with pounds displayed, pressing this key will
change the weighting units to kilograms. NOTE! This feature must be enabled
during setup and calibration for this key to be operational.
This key is used to lock and unlock the display. If the HOLD feature was
enabled during setup and calibration, pressing this key (after obtaining a stable
weight) will cause the indicator to lock onto the weight. Pressing this key again
will unlock the display and return it to zero.
If AUTO LOCK feature was enabled, weight display will lock after placing a load
on the scale and obtaining a stable weight. Pressing this key will unlock display
and return it to zero, or if another load is applied, lock onto new weight after
obtaining a stable weight. NOTE! The lock feature is for non-commercial (NOT
"Legal for Trade") applications.
BMI / ENTER
The BMI / ENTER key serves several purposes. First, during
setup parameters, pressing it will display the current setting of the
parameter. Second, it is used to signal completion of the data
entry and causes the indicator to process the data entered. Third,
it is used during normal operation to enter the height (feet and
inches or centimeters) for the Body Mass Index (BMI) calculation.
NOTE! The indicator will not respond to pressing the
BMI / ENTER key unless the weight display is stable.
Arrow Keys
The arrow keys are used during setup and calibration to select setup values. During operation,
they are used to increase or decrease the BMI height values.
Pressing the aor bkeys will increment or decrement the value of the selected digit. Pressing
the _or `will move the cursor (blinking character) to the next character position. Pressing the
BMI / ENTER key will save the value entered and advance to the next prompt. Note, that
when moving through the setup prompts, the default or previously selected value appears first
on the display.
Pressing the aor bkeys during normal operation will enter a weight recall option allowing the
last 10 weights recorded to be reviewed. The weight is recorded each time the weight is
locked. The ZERO key can be used to clear the recorded values. Use the aor bkeys to
scroll through the 10 records. Press any other key to return the indicator to normal operation.
NOTE! While reviewing the recorded weights, the display will alternate between the
