Battery Pack Operation
See the addendum page 24 for quick operational instructions on this feature.
Description
The Battery Pack Option will allow the scale to be operated in areas where no power is available. The battery pack itself is
installed inside the indicator housing and is not user serviceable in any way. The only external differences are the addition of
a Main Power toggle switch and power transformer connector located on the right side of the indicator housing.
To charge the pack, simply leave the scale plugged in for about four hours. The charging circuitry has a peak detect and will
stop charging once the battery has reached its peak. The scale may be operating normally while charging.
The battery pack allows a scale equipped with a single load cell platform (models 620 and 820) to operate for about fifteen
hours on a single charge. For scales that have multiple load cell platforms, running time is slightly shorter. A four load cell
platform, like the model 320 will run for about 8 hours.
The Main Power Toggle Switch
There is a main power switch located on the right side of the indicator. Its only function is to completely remove power from
the main circuit board in the event of a microprocessor program crash or any other event that causes the scale not to be
able to switch itself off. This toggle switch is also responsible for charging the battery. If the toggle switch is left in the open
(DOWN) position, then the battery will not charge. This toggle switch should be left in the closed (UP) position during all
normal operation.
The Front Panel On/Off Switch
The front panel On/Off switch is used to switch the scale on and off during normal operation.
To turn the scale on, simply press the button and the scale will start its initiation sequence. To turn the scale off, press and
hold this button for approximately three seconds until the display blanks out and then release it.
Auto Shutoff Setup
The scale can (and should) be setup to automatically turn itself off when a programmed time has been reached and/or there
is no activity on the scale. This is done through the Auto Shut-Off screen. You may also want to skip the splash screen and
ready prompt on startup. You can do this in the menu SETUP MENU/SYSTEM/STARTUP PARAMETERS.
The scale’s auto shutoff operation can be activated and changed in the menu SETUP MENU/ SYSTEM /AUTO SHUT-OFF.
There are two options available.
ACT
Activates/deactivates the auto shutoff feature.
TIME
Is the time, in minutes, that the unit will shutoff due to inactivity.
Statistical Package [N/A: For Future Expansion]
The Statistical Package allows you to save a large number of readings in memory for future use. Here are some of its
features:
You can transmit the entire data collection through the RS232 communications port to a printer or computer for later
analysis.
You can view a “result screen” which will show the minimum reading, the maximum reading, the average, and total.
The data collection is held in memory even if the power is removed.
Readings can be saved by simply pressing a key.
Shares m
emory with the scale’s operating system for maximum storage efficiency.
Main screen shows when data collection is active and the number of readings collected.
Statistical Menu
This menu contains all of the functions associated with the statistical package. It is located at SETUP MENU / OPTION
SETUPS / STATISTICAL.
The items in this menu are:
SETUP:
This is a simple configuration screen for the statistical package.
CLEAR MEMORY:
This will clear all collected data from memory.
