CHARGEMASTER 1500 SCALE INSTRUCTIONS:
GENERAL INFORMATION
The scale should be stored and used at
normal room temperature. It should never be
stored in cold or freezing temperatures, which
can damage the load cell. If the scale has
been sitting at a cool temperature, remove it
from the carton and allow it to sit at room
temperature for about 20 to 30 minutes before
using.
Carefully unpack the scale. Look for and
identify the following items:
n Scale with Platen
n AC Power Adaptor
n Two 50 gram weights
n Powder pan
n Instruction Manual
The scale was shipped in protective packaging
which should be saved and used for
transporting the scale. This packaging is also
recommended for long term storage of the unit.
POWER SUPPLY (ADAPTOR):
(1) Input : 120 VAC 60 Hz
Output : 9V DC 1 A
(2) Input : 230 VAC 50 Hz
Output : 9V DC 1 A
Power Consumption:
Average current consumption: 33 mA
Power consumption of dispenser:
Scale à 33 mA
Scale + Dispenser à 36 mA
Scale + Dispenser + motor à 220 mA (Max)
SPECIFICATION:
1500.0 grains / 0.1 grain
100.00 grams / 0.01 gram
IMPORTANT:
Treat the scale as you would any fine
instrument. The ChargeMaster 1500 is
physically very fragile and the load cell can be
damaged by the following:
n Pushing down or dropping the scale.
n Pulling up on the platen in such a
way that it binds in the load cell.
n A sudden, violent physical shock to
the scale.

Stable: When black arrow points to stable the
weight is stable
The remaining indicators are for use with the
ChargeMaster Dispenser
GN/GMS: Key switches scale from GN (grains)
to GMS (grams) . The default is GN.
ZERO: Key is used to re-zero the scale. For
example, to weigh powder in a powder
pan, you would first place an empty pan
on the scale platen and push the ZERO
key to re-zero the scale. This will
automatically subtract the weight of the
pan from the scale.
CAL: Key is used to calibrate the scale. You
should calibrate your scale each time
you begin a new reloading session.
See the calibration section for full
details. (Note: it is important to make
certain the scale display is properly set
to the weight unit (either grains or
grams) that you are using.
ON/OFF: Key is to power the scale on and off.
When you turn the scale on the display
will first show 9999999 and will go
through a quick count down and will
then display to 0.0 GN (grain mode).
The arrow will be pointing to "stable"
when ready to use. When the scale is
not in use the scale should be turned off
and unplugged.
CALIBRATION
Always calibrate your scale before use. This
must be done WITHOUT the powder pan on
the platform. To calibrate the scale, follow the
steps below:
Step 1.Be sure the powder pan has been
removed from the scale platen and then
press the ON key. When you turn the
scale on, the display will show 9999999
across the display for a few seconds
and then counts down to display 0.0
GN (grains mode). The arrow will be
pointing to "stable" when ready to

proceed with calibrating. SEE
PICTURE #1.
Step 2.Next press the CAL key on the scale.

The display will show C 0, with a lower
case g in the upper right hand corner of
the display. SEE PICTURE #2.
Step 3.When the display shows C 0 press the
CAL key again.
ON/OFF
Step 4.When the display shows C 50, place a 50
gram weight on the platen and press the
CAL key. SEE PICTURE #3
Step 5.When the display shows C 100, add the
second 50 gram weight to the platen and
press the CAL key. SEE PICTURE #4.
Step 6.Now the display will show 100.00 g, SEE
PICTURE #5. Remove both weights from
the platen, and replace them to their
weight holders. The display will
automatically switch to 0.0 GN (grains)
and the scale will sound a beep.
Step 7.Next place the powder pan on the platen
and press the ZERO key to zero the
weight of the pan. The display will show
0.0 GN and is now calibrated and ready
to operate. SEE PICTURE #6.
Notice: In the calibration process,
when it shows ERROR, it is probably
caused by the incorrect weight.
Please use the weights we provided.
