Congratulations on your purchase of the Lyman 1200 DPS (Digital
Powder System). This is a precision piece of equipment and should
be handled with care. Before using the 1200 DPS Powder
Dispenser, please read these instructions fully and become familiar
with the key pads and other operating features listed in the
diagrams. If you have read the instructions and you still do not
understand some of the operations, call us at 1-800-22-LYMAN
except AK, HI, CT and foreign, who may call 860-632-2020. This
operation manual should be kept with the 1200 DPS at all times for
easy reference.
Introduction
Your New 1200 DPS (digital powder system) is the state of the art
in reloading technology. It is the fastest powder dispenser
available and contains a programmable memory to store and recall
all of your favorite loads quickly and easily.
A. Set-Up
1. Select a location for the 1200 DPS that is level and stable.
It is recommended that the 1200 DPS be located away from
a loading bench equipped with a reloading press. Most
benches are not heavy enough to prevent vibrations being
transferred to the scale. The scale should also be away from
any source of air currents. The 1200 DPS is sensitive
enough to have readings affected by any of these
condit ions.
2. Plug the power adapter into a wall outlet and connect it to
the dispenser. Install the powder reservoir tube by pressing
it into the top of the unit above the feed tube.
3. Remove end cap from powder feed tube.
B. Warm-Up and ON/OFF
1. Press the ON/OFF button to turn on the 1200 DPS.

2. The 1200 DPS is equipped with an automatic 30-minute
warm-up feature. This feature allows the precise electronics
time to stabilize. The LCD display will alternate between
warm-up and a count down clock. In the warm-up mode,
the scale, powder dispenser and calibration features will be
blocked, however, the user can still enter settings into the
memory as well as recall and edit existing memory. We
recommend that the scale be allowed to fully warm-up
before use to ensure the highest accuracy level. If this is not
possible, the warm-up mode can be cancelled by pressing
the CANCEL button. This will allow full access to all of
the 1200 DPS functions, however, accuracy could be
slightly reduced until full warm-up is reached.
3. To turn off the 1200 DPS, press and hold the ON/OFF
button. The 1200 DPS will return to the warm-up mode if
the power is shutoff for any length of time. Always turn off
the 1200 DPS using the ON/OFF button first, and then
unplug the power transformer.
C. Calibration
1. After warm-up (or if cancel is pressed to exit warm-up) the
unit will be in Scale and Dispense mode. We recommend
that the scale be calibrated before use. This should be done
without the powder pan on the platform.
2. Press the CAL/ZERO button to reset the scale to zero.
3. Press and hold the CAL/ZERO button. The LCD will
display “Cal 20g”.
4. Place the 20 gram weight onto the platform and press the
CAL/ZERO button again. (Press and Release – Do Not
Hold)
5. The LCD will display 0.0 Remove the 20 gram weight. The
LCD will display approximately -308.6.
6. Press CAL/ZERO one more time to reset zero.
