Getting Started
5
1. Carefully remove the scale and all of its components from the packaging
and place it on a stable base where the scale will not be affected by any
mechanical vibrations or air movements.
2. After removing the pan base and the pan from its packaging, carefully
install the pan base onto the scale by placing it on the pan support located
in the middle of the scale. Once the pan base has been installed, carefully
place the pan on the base as shown below.

3. Once the pan has been installed, level the scale by adjusting the rear feet
until the level indicator shows the “air bubble” is in the center position of the
sight glass. The level indicator is located in the rear left side of the scale.
4. After leveling the scale, plug in the AC adaptor to the AC adaptor socket
located in the rear of the scale.

5. When the AC adaptor is plugged into the wall outlet, the scale will turn
“ON” automatically, go through its initiation process, and enter Weighing
Mode.
To put the scale into Standby Mode, leave the AC adaptor plugged into both
the scale and the wall outlet and press the Power “OFF” button ( ). The
“OFF” indicator will light up in the upper left corner of the display signaling
the scale is in Standby Mode, i.e.:

To begin weighing, press the power button ( ) to turn the scale ON. The
scale will go through its initialization procedure and automatically enter
Weighing Mode. The scale is ready to begin weighing as soon as the
stabilization ( ) and center of zero ( ) indicators appear on the display,
i.e.:
1.

2. When weighing, always place the mass in the middle of the pan. The
weighed result may be taken when the stabilization indicator appears on
the display, i.e.:

1. The DRX-4 is armed with AZSM, the “Auto Zero Setting Mechanism.”
AZSM automatically maintains a “center of zero” condition within +/- .6d
or 6mg
2. The scale may be re-zeroed manually to obtain a new “center of zero.” To
re-zero the scale manually with a weight that is out of the AZSM range,
make sure the weight and the stabilization indicator are shown on the
display, i.e.:
3. Re-zero the scale by pressing the zero button.
4. The display will show a dotted line, which indicates the scale has begun
the re-zeroing process, i.e.:
WARNING: Do not touch or move the scale during the
re-zeroing process.

5. When finished re-zeroing, the scale will return to Weighing Mode and the
display will indicate 0. A new center of zero has been set, and the scale is
ready for weighing.
Taring

Weighing Mode
after it has been
re-zeroed
1. If a container is used for weighing, it may be tared. In taring the container,
the scale subtracts the weight of the container from the gross weight to
obtain the net weight.
2.
To tare the weighing container, place it in the middle of the pan. The
container’s weight will be shown on the display, i.e.:
Note: Re-zeroing the scale will reduce the capacity of the scale by the re-
zeroed weight. The remaining capacity is displayed as a percentage on the
right side of the display.

3. Once the stabilization indicator appears on the display, the container is
ready to be tared. To tare the container, press the “T” button. The display
will show a dotted line which indicates the scale has begun the taring
process, i.e.:
4. When finished taring, the balance will return to Weighing Mode. The
display will indicate 0, and the NET indicator will be shown on the display
signaling the next weight taken is a NET result.
WARNING: Do not touch or move the scale during the taring process.

Note: Taring and re-zeroing are two completely separate functions. Once
the scale has been tared, it may not be re-zeroed until the tare is cleared.

Clearing the Tare
1. To clear the tare, remove the tared object along with the NET weight from
the pan. The scale will then display a negative NET tare result.

The printing function is used to print data via the RS232 port. Data may be
printed via a printer or sent to PC software. The printing function is pre-set; it
is automatically enabled each time the scale is turned ON. To turn the printing
function OFF or ON, follow the steps below:

Calibration
1. Once the scale has its power ON and is in Weighing Mode, use a flathead
screwdriver to gently remove the Calibration Seal Screw located in the
rear of the scale.
Display in
Calibration Mode
Calibration of the DRX-4 should be performed with a single accurate 100g
weight. To Calibrate the scale follow the directions below:
2. Once the screw has been removed and the calibration switch exposed,
use a pen or another pointing device to toggle the calibration switch to the
right (which is the ON position.)
3. Upon toggling of the calibration switch, the balance will go into Calibration
Mode. For approximately five (5) seconds the display will read CAL,
indicating the scale is in Calibration Mode.

5. Once the scale has finished taring, the display will read “Load, 100g” which
indicates a single 100-gram calibration weight should be loaded. “Load,
100g” appears sequentially every two (2) seconds.
WARNING: Do not touch or move the scale during the
taring process.
