1.3 Operating Modes
The 482-AG has four modes of operation.
Weigh Mode
Weigh mode is the default mode of the indicator. The indicator displays gross weight, a transaction in process annunciator, the
universal standstill symbol and center of zero symbol, when conditions are met, to indicate scale status (Section 1.6 on page 4).
Configuration Mode
Most of the procedures described in this manual, including calibration, require the indicator to be in configuration mode.
To enter the configuration mode:
1. Remove the configuration switch access screw from the back of the enclosure. See Figure 2-1 on page 8.
2. Insert a non-conductive tool into the access hole and press the configuration switch. The indicator display changes to
CONFIG mode.
Test Mode
Test mode provides a number of diagnostic functions for the 482-AG indicator including:
• Display raw A/D count
• Number of weighments over threshold
• Reset configuration parameters to default values
See Section 3.5 on page 26 for more information on the test menu structure and the test menu functions.
Sleep Mode
Firmware version 1.03 and newer of the 482-AG features a sleep mode. This feature is designed to place the indicator into a
low power mode to reduce power consumption.
The sleep mode will activate only if the indicator is operating on the optional internal battery. If the indicator is connected to an
external AC power source, it will not go into sleep mode regardless of the parameter settings.
The indicator will enter the sleep mode, after a specified time when no keypad activity is detected and the displayed weight is
below the weight threshold. Setting the sleep parameter to NEVER disables the sleep mode. A Standby parameter determines
how often the indicator will briefly wake, while in the sleep mode, to check for activity thresholds. See Section 3.3.1 on page 25
and Table 3-7 on page 24 for information on configuring sleepmode and standby parameters

2.4 Battery Operation
The 482-AG can be equipped with an optional internal Lithium-Ion battery to provide up to:
• 40 hours of continuous use (single load cell, 350 ohms, no LCD backlight)
• 15 hours of continuous use (single load cell, 350 ohms, with LCD backlight)
When operated on AC power, the internal battery is automatically charged.
The status of the battery is displayed by an icon in the upper left corner of the LCD display. When operating on battery power,
the icon of the approximate percentage of battery life remaining displays. When connected to AC power, the icon indicates if the
battery is charging or fully charged. The following table outlines the meaning of the various battery icon indication levels.
Battery life depends on several factors, including number of load cells, frequency of use, LCD backlight, options installed,
temperature, and other accessories being used. Battery charge time is approximately 16 hours to 100%.
To extend battery life, the indicator features a sleep mode that allows the indicator to go into a low power mode while it’s
operating on battery power, see Section 3.3.1 on page 25 for more information about the sleep mode.
When the battery life reaches 5-10 percent of capacity, the Lo Bat flashes on the display. When the battery life is less than 5%,
it will flash faster. At 0% the indicator will turn off. Battery charge time is approximately 16 hours to 100%.
Figure 2-7. Battery Charging Cycle Example
When installing a 482-AG with a battery option, it is recommended that the CPU board jumper 4 on the A/D Board be
removed. See Figure 2-6 on page 10. Removing jumper 4 will maximize the life of the battery when the indicator is
turned off due to reduced standby current, see the POWER parameter in Section 3.6.6 on page 35 for more
information.
2.5 Configurable Back Light
The 482-AG includes a configurable LCD backlight for viewing the display in low-light situations. The backlight can be
configured to be On, Off or in Auto Mode. Configure the backlight using the BKLGHT parameter, see Section 3.6.6 on
page 35. When using battery power, use the off or automatic setting to reserve power.
The backlight consumes considerable power. When the automatic setting is selected, the backlight will go out after a set time of
inactivity. Pressing a key or any motion on the scale will activate the backlight.
The backlight is configured using the BKLGHT menu function. To set Auto Mode, select one of the fixed time settings between
10 seconds and 10 minutes. The backlight will turn off when there has been no change of motion or key presses during the
selected time. The backlight will turn back on automatically once there is a change in motion or a key pressed.
