CONTROL PANEL 5 BUTTON ID
& EXPLANATION
1. POWER - Push this button once to turn the scale
on, while pressing it again to turn it off. When
powered on, the scale display will initially show
“999999” and begin a countdown boot-sequence
to initialize the scale. While in the gram mode,
the blue backlit display will then show 0.0g after it
stabilizes. The scale will automatically display the
last unit of measure (g, dwt,ct, gn, oz, mom, ozt &
lb) that was programmed into the scales memory.
2. TARE - Push this button once to bring the scales
display back to 0.0g while in the gram mode (this
feature may be used in any mode). When using a
weighing tray or other type of scoop or container,

5INSTRUCTION MANUAL
simply place the tray, etc. on the weighing platform
and then push the TARE (zero) button once to
automatically subtract the weight of whatever was
on the weighing platform while maintaining the
subtracted weight in its memory. The display will
then show 0.0g. If you then take the tray off of the
weighing platform, from its memory the display
will show a negative weight equal to the weight of
the tray or whatever was on the weighing platform.
After placing the tray back on the weighing
platform, you may then place the item that you
wish to weigh directly into the tray and weigh it
independently. When you no longer wish to use
the tray, you may press the TARE button once
again to bring the display back to 0.0g or press
the POWER button once to turn the scale off since
both of these steps will subtract the weight from
its memory.
3. CAL – Push and HOLD this button to initiate the
scale’s calibration process. To calibrate the scale,
please refer to the CALIBRATION PROCEDURE
section noted below.

GEMORO PLATINUM PRO1001DXP ITEM #9780 6
Pushing this button also changes the decimal
place in the weighing mode you are using. The
units of measure are as follows per weighing mode:
Gram (g) - 0.1 or 0.01
Pennyweight (dwt) - 0.1 or 0.01
Carat (ct) - 0.1 or 0.01
Momme (mom) - 0.1 or 0.01
Grains (gn) - 1 or 0.1
Ounce (oz) - 0.01 or 0.001
Troy Ounce (ozt) - 0.01 or 0.001
Pounds (lb) - 0.001 or 0.0001
4. PCS – Push this button to initiate the scale’s
parts counting PCS feature. Please refer to the
COUNTING FEATURE (PCS) section noted below.
5. UNIT - Push this button to scroll through the
scale’s weighing modes. Simply press the button
once to scroll through each weighing mode until
you find the desired unit of measure.
6. PRINT - Once stabilized, use this button to print
the displayed weighing results to your thermal
printer. Please refer to the PRINTING section
noted below.

CALIBRATION PROCEDURE (Two-Point Calibration)
Once calibrated, the PRO1001DXP should maintain
its calibration unless moved, bumped or the weighing
environment has changed. For best results, it is
advisable to check the calibration at regular intervals
by placing a known mass or weight or the supplied
(2) 500g calibration weights on the scales weighing
platform. If calibration is required, please carefully
follow these steps:
CAUTION: Never attempt to calibrate the
PRO1001DXP unless you have the required (2) 500g
calibration weights with the scale handy.
1. Press the POWER button to turn the PRO1001DXP
on. Allow the scale to warm up and stabilize for
approximately two minutes before commencing
with the calibration procedure.
2. Remove all items from the weighing platform and
press the TARE button to zero the display.
3. After observing a stable 0.0g while in the (g) gram
mode, press and hold the CAL button and “CAL”
will appear on the display.
4. Press the CAL button again. “CAL” will begin
flashing and then after a few seconds “500.0g” will

GEMORO PLATINUM PRO1001DXP ITEM #9780 10
begin flashing on the display.
5. Gently place a single 500g calibration weight near
the center of the stainless steel weighing platform.
Be sure to leave space on the platform for the
second 500g weight. IMPORTANT- Do not disturb
the PRO1001DXP during this time as it may impact
the accuracy of the calibration.
6. Approximately 4 seconds after the first 500g
weight is placed on the platform, the display will
then change to read “1000g”. Gently place the
second 500g calibration weight onto the stainless
steel weighing platform, so that the total weight on
the platform will then be 1,000g.
7. The display will then show “PASS” which indicates
that the calibration procedure has been successful.
If “Err1” appears on the display instead of “PASS”,
this indicates that an error has occurred, and the
calibration procedure should be repeated.
PARTS COUNTING (PCS) FEATURE
The parts counting (PCS) feature within your scale
can be really handy if you are in need of counting a
large number of small items (example: findings, silver
beads, gold chains, etc.) very quickly and accurately.

11INSTRUCTION MANUAL
By weighing a minimum sample of 25 pieces of an
item, the scale will determine the average weight of
each piece and use that as its reference. (Note: The
larger the sample size used, the greater the accuracy
of the per piece count.) Once the reference sample
weight has been determined, you may place an
unknown quantity of the item on the scale and it will
automatically count the exact number of pieces.
1. To set your PRO1001DXP to the parts counting
mode, once the scale has been turned on and it
has stabilized, place either 25, 50 or 100pcs of the
item you wish to count onto the weighing platform.
2. Press and hold the PCS button for 2 to 3 seconds.
The screen will begin to flash a quantity (25, 50 or
100). To select a specific quantity, press the UNIT
button and continue to press the button repeatedly
while scrolling through the various units of
measure until the display reads the same sample
quantity you have placed onto the weighing
platform.
3. Press the PCS button again to lock the sample
size used into the counting program. The display
will then read “pcs” in the upper left hand corner
of the display to indicate that the PCS function is

GEMORO PLATINUM PRO1001DXP ITEM #9780 12
enabled.
4. You may switch between the scales PCS mode
and regular weighing by pressing the “PCS button.
The scale will continue to retain the last “PCS”
setting made until you go through the above
process again.
5. In many cases when counting very small or round
parts, etc. it is suggested that a weighing tray
(scoop or container) be used to hold the items.
PRINTING FEATURE
With the push of a button, the printing feature
allows you to record the weight of items on paper
when using an attached thermal printer that has
been interfaced with the scale. The scale has both
standard USB interface and RS232 serial port
capabilities. Simply follow the below steps to set up
the printing feature on your scale:
1. Ensure that the USB cord is connected to your
scale and plug the opposing end into your thermal
printer.

13INSTRUCTION MANUAL
2. Place an item on the scale platform. When the
weight reads “stable”, you may then press the
“Print” button on your scale to send the reading to
your thermal printer.
