III. About your Presidium Carat Scale
The Presidium Carat Scale utilizes a strain gauge
load-cell to provide output in terms of millivolts, which is
then converted to weight by a micro-controller inside the
scale.
The Presidium Carat Scale features the following:
• Four conversion options (gram, carat, ounce, grain)
• Three trays for di󰀨erent uses
All Presidium scales are factory calibrated. Currently

IV. IMPORTANT NOTICE
• Keep the tester dry. Precipitation and all types of
liquids or moisture can contain minerals that will
corrode electronic circuits. If your tester does get wet,
remove the battery, and allow the tester to dry
completely before replacing it.
• Do not use, store or expose the scale in dusty and dirty
areas. Its moving parts and electronic components can
be damaged.
• Do not use, store or expose the scale in hot areas.
High temperatures can damage or shorten the life of
the tester, damage batteries, and warp or melt certain
plastics.
• Do not use, store or expose the scale in cold areas.
When the tester returns to its normal temperature,
moisture can form inside the tester and damage
electronic circuit boards.
• Do not attempt to open the scale other than as
instructed in this handbook.
• Do not drop, knock, or shake the scale. Rough
handling might break internal circuit boards and ne
mechanics.
• Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the scale.
• Do not paint the tester. Paint can clog the moving parts
and prevent proper operation.
If the tester is not working properly, kindly contact
Presidium Customer Service at [email protected].

1. GETTING STARTED with your Presidium Carat
Scale
Powering up your Presidium Carat Scale
This scale can be powered by either the use of an AC
adaptor (optional item sold separately) or through the use
of batteries. If AC adaptor is used, connect one end of the
AC adaptor to the tester and the other end directly into a
suitable electrical outlet (Fig 1.1). Please ensure that only
the adaptor supplied by Presidium is used.
Fig. 1.1
Fig. 1.2
If batteries are used (4 x AAA batteries), take note of the
positive (+) and negative (-) directions of batteries when
inserting the batteries into the scale (Fig. 1.2). The use
of alkaline batteries is preferred, as it should generally
give approximately two and a half hours of continuous
operation, while the use of ordinary batteries will give a
shorter working life.

Fig. 1.3
Press the [ON/OFF] button (Fig.1.4) to turn on the scale
All segments on the Display should blink three times
(Fig. 1.5). for self-testing to ensure that the LCD is
functioning properly.
Fig. 1.4
Fig. 1.5
Turning on your Presidium Carat Scale
Place the scale on a at level surface. Lift the transparent
lid. Place the tray on the weighing arm, then close the lid
(Fig. 1.3).
10

Calibration
PCS-50LFT is calibrated according to the surface gravity
of the location which is indicated on its packaging as well
as on the LCD window. Due to di󰀨erences in surface gravity,
for permanent usage in other cities, please send the unit
back to the manufacturer for recalibration.
Recommended testing conditions
The recommended testing temperature is 18°C – 27°C
or 65°F – 80°F.
In case of change of working environment or
temperature change exceeding 5°C, allow the unit to set
for 30 minutes before using.
Battery information
Stop using the unit when the low battery indicator is
displayed to prevent inaccurate measurements.
Do not leave worn out batteries in the
battery compartment as the batteries may
corrode, leak or damage the scale. Batteries should be
removed when the instrument is expected
to be stored for an extended period of time.
To prevent inaccurate readings, replace with new
batteries as soon as the low battery
indicator lights up or starts to blink. A test should not be
performed when the battery power is low or weak.
Batteries do not have to be removed when the AC
adaptor is in use.
11

2. PERFORMING A TEST with your Presidium Carat
Scale
Place the gemstone to be measured on the weighing tray
(Fig.2.1). after the word “READY” appears. The result
will be displayed immediately on the LCD. For accurate
reading, take the reading only after the word “READY”
appears.
Fig. 2.1
For conversion between di󰀨erent measuring units, press
“g/ct” to toggle between ‘gram’ or ‘carat’ or press “gr/ozt”
to toggle between ‘grain’ or ‘ounce’.
Tips for using your Presidium Carat Scale
Keep the transparent lid closed when scale is in
operation.
The [EEEEE] sign appears when the weighing range
exceeds 50ct/10g weighing capacity.
It is advisable to take multiple readings if any doubt exists
regarding the test results indicated.

3. TROUBLESHOOTING your Presidium Carat Scale
[CAL] does not stop blinking:
• The calibration weight was removed from the tray
during calibration and calibration was terminated. The
calibration process must be repeated.
[Error] sign appears during calibration:
• The calibration weight was placed onto the tray before
the [CAL] started blinking.
[Err LO] sign appears during calibration:
• The calibration weight is below the standard weight
(10g).

4. TAKING CARE of your Presidium Carat Scale
• For accuracy of reading, avoid shocks (such as
dropping the instrument) or vibrations to the unit. Do
not shake or cause impact to the unit.
• Do not attempt to dismantle the unit.
• Do not leave worn out batteries in the battery compartment
as the batteries may corrode. Batteries should be
removed when the instrument is expected to be stored
for an extended period of time.
Your scale is a product of extensive design and craftsmanship
and should be treated with care.
Thank you for taking time to go through the user handbook
which will enable you to understand your recent purchase
better.
