Quick Start
To operate the OCTA-WIRELESS as a basic weigh scale, perform the following steps:
Setup
1. Unpack the scale as described in the “Unpacking the OCTA-WIRELESS” section below.
2. Install the batteries into the control box as described in the “Battery Installation” section
below.
3. Place the Weighing Platform on a firm, level surface.
4. Push the On/Off button on the transmitter, Led Indicator will begin to blink.
5. Turn the OCTA-WIRELESS on by pressing on the control box.
6. “88888” will appear on the display, after 3 seconds of establishing the connection with
the transmitter, the figure “0” will appear.
7. If connection cannot be established after 10 seconds, “err” will appear on the display
and the device will automatically shut off. In this case, check the battery condition and
ensure that the distance between the scale and the control box does not exceed 10
meters (33 ft)
8. Select the proper measurement units by repeated pressing . The units will cycle as
follows:
kilograms Öpounds Öpounds and ounces Öounces
9. Select the desired display resolution by repeatedly pressing as described in the
RESOLUTION section.
Basic Weighing Operation
1. If using a container to hold the objects being measured, place it empty on the center of
the platform.
2. Press to “zero-out” the scale. The display will read zero.
3. Place the material to measure in the container or on the center of the platform.
4. Read the weight on the display.
5. A positive number indicates the applied weight is greater than the zero value. A
negative number indicates the applied weight is less than the zero value.
6. Turn the OCTA-WIRELESS off by pressing down until the scale turns off.

Stand-by Mode
After shutting off the device, it will remain in stand-by mode for 25 minutes. By pushing
the button during this time the scale can be reactivated without separately turning on
the transmitter.
If no activity happens for 25 minutes, the transmitter shuts off automatically.
Unpacking the OCTA-WIRELESS
1. Remove the OCTA-WIRELESS from the carry bag.
2. Push the signed part of the control box to remove it from the storage dock. The storage
dock is placed on the low side of the weighing platform.
3. Pull out the control box from the storage dock.
4. If desired, extend the mounting hook.
5. Open the battery cover on the transmitter and install the batteries.
Repacking the OCTA-WIRELESS
1. Fold in the mounting hook.
2. Push the control box firmly into the storage dock of the weighing platform until it snaps
into place.
3. Replace the OCTA-WIRELESS into the carry bag.
Battery Installation & Replacement
1. Remove the battery cover by compressing tab at the base of the battery cover.
2. If necessary, remove old set of batteries.
3. Insert 4 ‘AAA’. Replace battery cover by aligning tabs and snapping back into place.
IMPORTANT: TO PREVENT DAMAGE TO THE OCTA-WIRELESS, CAREFULLY
OBSERVE BATTERY POLARITY AS MARKED INSIDE THE BATTERY COMPARTMENT.
DO NOT LEAVE DEAD BATTERIES INSIDE THE CONTROL BOX. REMOVE
BATTERIES IF THE OCTA-WIRELESS IS NOT TO BE USED FOR AN EXTENDED
PERIOD OF TIME.

Resolution
The resolution (minimum incremental weight or volume) thatcan be displayed by the
OCTA-WIRELESS can be adjusted to make the display easier to read. Unstable loads or
high winds can cause the display to fluctuate erratically. By reducing the display resolution,
external influences can be minimized. As shipped, the OCTA-WIRELESS is set to MEDIUM
resolution, suitable for most purposes. The resolution can be changed to LOW, MEDIUM or
HIGH by repeated pressing on the keypad. The table 1 illustrates the displayed
resolution for each units mode vs. resolution. Regardless of the resolution setting, the scale
operates internally with the highest resolution; therefore, only the displayed value is affected.

Over Range Indication
If the weight applied to the weighing platform exceeds the maximum capacity of the OCTA-
WIRELESS (100 kg), a single “1” will be shown on the left side of the display. To prevent
damage to the OCTA-WIRELESS, immediately remove the weight from the platform.
Hold Mode
A special feature of the OCTA-WIRELESS allows the emptying or replacing of bins or
containers used for weighing without affecting the weight shown on the display. This Hold
Mode may be used as follows:
1. Allow load to settle until display is steady.
2. Press . The current weight is now locked on the display.
3. Remove, empty, or replace objects, bins, or containers on the platform.
4. Wait 5 seconds for the new load to stabilize.
5. Press . Measurements will continue from where they left off prior to initiating Hold
Mode.
Programming
With the OCTA-WIRELESS, a programmable threshold weight will sound an alarm. The
alarm will sound when the displayed weight (either positive for increasing weight, or
negative for decreasing weight) equals the programmed weight. To program the alarm,
perform the following steps:
1. Set up the OCTA-WIRELESS with the desired units and resolution as described in the
Quick Start Setup section above.
2. If measuring decreasing weight, place the objects or container with the objects or
material that will be removed on the weighing platform.
3. Press to start the SET Mode, indicated by the SET enunciator on the LCD display.
4. Press and/or hold the or keys to set the desired alarm set point. To change the
set point faster, press . This will activate the FAST SET mode which will change the
set point 10x faster than normal. Press again to return to the normal speed SET
mode.
