Getting Started
5
1. Carefully remove the scale, pan,
scanner, and all of its components out
of the packaging and place them 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 their 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.
Instruction Manual Model DRX-4C
3. Connect the scanner to the scale by plugging in the RJ connector to the
scanner and the RS232 connector to the scale. The RS232 port is
located in the rear of the scale. Using a small flat-head screwdriver,
tighten the connector screw to secure the cable and prevent it from
unintentional unplugging.

4. Once the pan and scanner have 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.
5. After leveling the scale, plug in the AC adaptor to the AC adaptor socket
located in the rear of the scale.

6. 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.:

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.:
Zeroing the scale

accurate 4g result
1. The DRX-4C 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
Display in the
Weighing Mode
after it has been
re-zeroed
1. If a container is used for weighing, it may be tared. When 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.

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.
2.
To clear the tare, press the T button.

Compounding (Recipe Making)
1. Place the container for your recipe in
the center of the pan.
2. Tare the container by pressing the T key.
(For more on taring, please turn to Chapter 8 of this manual.)
3. Once the first tare has been taken, the scale will automatically activate the
summing function which will help you in adding all of the ingredients. The
display will show SUM to indicate this function is activated.

SUM has been
activated
4. Place the first ingredient in the container and wait until the weight is
stable. i.e.

The DRX-4C is an excellent tool for compounding and recipe making. The
compounding feature will help you in adding up all of your ingredients as well
as printing the details of your recipe. To compound, follow the steps below.

5. Press the T key to prepare the scale for the next ingredient. The weight of
the ingredient will be tared and stored in the scale's internal memory.
6.
The scale will read zero indicating it is ready to receive the next ingredient.
7.
Place the second ingredient in the container and wait until the weight has
stabilized.

To add up and check the total weight of the ingredients at any time, press
the sum button ( ). The TOTAL weight of the ingredients in the container
will appear on the display for approximately 5 seconds. To continue
compounding, simply wait until the total weight disappears from the
display and press the T button to enter the next ingredient.

operation before freezing the display with the total compound weight. The
detail will not print once the display locks the total compound weight. For
more on printing, please turn to chapter 11 of this manual.
Printing the Recipe
1. To print a recipe at any time during the compounding process, simply
press the P button. The display will read PRINT indicating that printing is in
process.
