All our equipment is assembled, tested and packed with great care, if you might find something which is not
according to your expectations, please contact us immediately.
The RA Series scale is a high precision weighing instrument, which has to be approved and stamped by Weights and
Measures. This scale is stamped in our production plant or by your local Weights & Measures office. Please check
the stamping stickers on the scale before use.
Please read this instruction manual carefully.
Properly used and maintained, this scale will provide years of accurate weighing. Please handle it as you would any
piece of fine electronic equipment.

Precautions
This chapter gives detailed instructions and important information to install the RA Series scale successfully.
Environment
EnvironmentEnvironment
Environment
Before you install your RA Series scale, identify the best location for the equipment. The proper environment
enhances the operation and longevity of the scale. Keep in mind the following factors, which might have a negative
influence on the scale's operation:
✦ ibration
ibration diminishes the scale’s ability to measure accurately. Electrical machinery such as conveyors and drill
presses can cause inaccurate and non-repeatable readings. The scale may also read inaccurately if it is not leveled
properly.
✦ Air current
Moving air can cause the scale to read an additional force (add. weight) and have the same effect as vibration.
✦ Friction
A scale cannot measure accurately if an object is rubbing or pressing against the platter.
Unpacking and inspection
Unpacking and inspectionUnpacking and inspection
Unpacking and inspection
Please inspect the package as it is delivered by the carrier. If the shipping container is damaged, check for internal
damage and file a freight claim with the carrier if necessary. If the container is undamaged, open the box, remove the
scale and place it on a solid, flat surface. Please keep the packing material and shipping insert in case you need to
return the scale to OHAUS. The RA Series is a precision instrument and may be permanently damaged if not shipped
in factory approved packaging.
Package contents for all RA Series units include:
✦ RA Series scale ✦ platter ✦ AC-DC power adapter ✦ operation manual
Setup
SetupSetup
Setup
Open the box and pull up the scale, including the packing material. Remove the packing material from each side of
the scale.
Set the unit on a sturdy, level surface. Level the scale by turning the adjustable feet on the bottom of the unit. When
the bubble indicator is in the centre of the circle, RA Series is levelled correctly.
Bubble indicator: Good Wrong
All four feet must touch the surface to make sure that the RA Series does not rock.
Put the platter on top of the RA Series.
Unpack the power adapter and plug it into the bottom of the scale. Plug the line cord into a properly grounded AC
power outlet.
Power up sequence
Power up sequencePower up sequence
Power up sequence
Press the power key to turn on the RA Series. The RA Series goes through a series of self-tests when it is turned on.
The scale performs a diagnostic test on its ROM and RAM, and proceeds to normal operating mode. The power-up
sequence is as follows:
• Light all segments of the display characters. This verifies operation of all segments.
• Display the software revision and part number.
• Display GEO value in weight window.
• Capture zero and be ready for normal operation.
Note: Before switching on the RA Series scale, always make sure there is nothing on the platter.

There are two ways to re-zero the scale:
1. Power-up Zero
2. Push button Zero
✦ Power-up Zero
The scale will automatically capture zero when it is turned on. The power-up zero capture range is +/-10% of
the scale capacity. When the scale is turned on with a weight on the platter of more than +/-10% of the
capacity, the scale will not capture zero (the weight display will show "-----") and the scale will not be ready
for use. After removing the weight the scale will capture "zero".
>0<
✦ Pushbutton Zero
The ZERO key re-zeros the scale over a range of +/-2% of the scale capacity. To use this function, the scale
must be in the gross weighing mode (NET cursor must be off) and in a no motion condition. When the weight
on the platter is more then +/-2% of the scale capacity the depression of the zero key will not be accepted.

Power Saving Feature
Power saving feature is used to save battery power.
When using the battery and the scale is idle for 2 minutes, both the price and total price displays will turn off, the
weight display will only display one 0 on the right and the battery in use cursor is lit. This indicates that the scale is
in the power saving cycle. When weight is placed on the platter or a key is pressed, the scale will wake up
automatically.
If there is still no key operation and weight change 15 minutes after power saving status occurred, the scale will
be turned off automatically. This function can be enabled or disabled through setting of the softswitch (group 1,
step 4: “Automatic Power Off”).

If charging kit is installed, the scale can charge the lead-acid battery (6 /5Ah). To charge a lead-acid battery,
connect the scale to the external power supply. The battery will be charged regardless the scale is on or off.
It usually takes not more than 12 hours to charge the battery to full capacity depending on the voltage of the
battery. If the battery is has been deep-discharged, a prolonged charging time is required to bring the battery back
to full capacity.
There are two battery cursors, one is , and the other is
(-)
. Cursor is lit to indicate the battery capacity is full
and current power source is power supply, and it flashes to indicate that battery is being charged. Cursor
(-)
is lit
to indicate that current power source is battery, and it flashes to indicate that voltage of the battery is lower than
the required.
The scale shows “L Bat” in the weight window and stop weighing when the cursor
(-)
begins blinking, and the scale
will be turned off automatically about 10 seconds later. In this case, please charge the batteries.
If the unit is plugged into the wall outlet when battery power is used, the power source will automatically switch to
the wall transformer. And when the AC power is off, power source will automatically switch to battery.

The battery should be recharged at least every 5 months regardless it is used or not. After a long time storage, e.g.
over 3 months, it is desired to cycle (charge/discharge) the battery 3 times to let it restore to full capacity.
When replacing the battery, pay much attention to the poles. The positive (+) terminal must be connected to the
red connector and the negative (-) terminal must be connected to the black connector. If connected wrongly, the
battery will be damaged.
Several parameters in the scale can be changed to
