WARNINGS AND CAUTIONS: 
 
 
 
• If the 1200 DPS does not read zero on the display, 
DO NOT DISPENSE POWDER.  The scale must 
be zeroed before use. If powder is dispensed with a 
scale that does not read zero, the charge will not be 
correct and could be dangerous.  
 
• Be careful not be get powder between the platform and 
the scale body. This can affect scale readings. If powde
r
does drop into this area, carefully remove it with the
supplied brush. Do not attempt to remove the platform. 
 
• Slide switch on underside of unit is to set the (Hz). This 
is factory preset for domestic models and should not
need to be changed. Should you have a problem with
your scale, make sure the switch is set to match the input
voltage on the power adapter. Domestic 115V is 60 Hz
and 220V is 50Hz.

							 4 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 
co nd it io ns. 
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.  
						

							 52.  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 st ill enter settings into the 
memory as well as recall and edit exist ing 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 o f 
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 o f t ime. 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. 
  
						

							 6 D.  Scale and Dispense Mode 
1.  The scale and dispenser are now active.  Place the powder 
pan onto the platform and press the CAL/ZERO button to 
zero the scale. 
2.  Place the desired smokeless powder (black powder or 
Pyrodex should NEVER be used) into the powder 
reservoir. 
3.  The scale will read in grains (default) unless changed. To 
select the weighing unit desired, press the UNIT button to 
select the appropriate grains, grams or ounces.   
4.  Key in the desired charge weight using the keypad. If you 
make a mistake press the CANCEL button to clear the 
complete charge weight or press BACKSPACE to clear 
the last digit. While the desired charge weight is displayed, 
press the ENTER button to dispense powder. The 
dispenser will stop automatically when the selected charge 
weight is reached. We recommend that the first several 
charges be placed back into the reservoir. This allows the 
1200 DPS to fully stabilize and fill the charge tube with 
powder. After a charge is dispensed, the LCD will display 
“CT=001” indicating the first charge for 2 seconds. This is 
a count of the number of charges that have been dispensed. 
5. Press the ENTER button again to dispense another charge 
at the selected weight in memory. 
6.  To pause the dispenser while a charge is being dropped, 
press the ENTER button.  Press the ENTER button again 
to resume charging. 
7.  The dispenser will continue to drop the selected weight 
until it is changed. To change the selected weight, key in a 
new weight on the keypad and press the ENTER button. 
The dispenser will drop the new selected charge weight. 
 
D-2 Manual - Trickle Mode 
 
To manually dispense a charge, press and hold the FAST 
button. The dispenser will run the feed tube at high speed until 
the button is released. Press and hold the TRICKLE button to  
						

							 7run the dispenser at low speed. The feed tube will turn slowly 
until the button is released. 
 
D-3 Auto - Trickle Mode 
 
You can speed up the dispensing process by adding powder to 
the powder pan and then bring it up to the selected weight by 
pressing the ENTER button. By utilizing a powder measure to 
add almost all the powder to the powder pan and using the 
dispenser to automatically finish trickling to the exact weight, 
the dispensing time will decrease considerably. 
 
E. Storing New Memory 
 
The 1200 DPS will store up to 20 of your favorite loads in 
memory. Each load in memory has three input lines. 
    Cartridge Name    C=___

A load is not stored in memory unt il all t hree input lines

Cleaning The 1200 DPS 
 
Caution: Do not turn unit upside down and shake as 
this could harm the load cell. 
The cleaning procedure listed below may seem difficult, 
but after you become familiar with the dispenser it is 
relatively easy. The 1200 DPS was designed to be 
sufficient ly disassembled for thorough cleaning 
 
The 1200 DPS must be cleaned after use or when changing 
the type of powder.  It is Strongly recommended that 
powder NOT be left in the powder dispenser when finished 
loading or when putting it away as you may forget what
