Table 1: Common calibers that work with each insert
*For calibers not listed, insert a case into the station you are going to set up your Powder Check
Alarm then thread the Powder Check Die in and leave loose. Move the Tool Head to the down
position and drop in each insert starting with the Small Insert. The correct insert will be able to
sit about 1/8” proud of the top of the die body with some die height adjustment.
2. Place a case under the station you want to set up the Powder Check Alarm then move the tool
head to the bottom. Thread the Powder Check Die into the station until the top of the insert is
flush with the top of the die and leave loose.
3. Slide the Powder Check Die Housing over the top of the die and make sure to push the housing
fully down onto the die body. Tighten the set screw on the back of the housing to lock in place.

4. Verify there is a battery in the housing, then begin to thread the die down slowly until the
buzzer starts going off, then go one last quarter turn and move the tool head to the top. Tighten
the thin hex nut on the die.
5. Choose your Powder Probe Tip for your caliber size. See below for the rod sizes for your caliber.
Figure 2: Powder Probe Tips.
6. Slide the Trigger onto the Upper Rod and drop them into the top of the die assembly, then take
the probe tip you chose and feed it up through the bottom of the die assembly. Thread the rods
together tightly. Note: You may apply purple Loctite to the rod threads to prevent loosening.

7. Place a case with the desired charge onto the shell plate under the powder check alarm station.
Move the tool head to bottom to verify your alarm triggers, if so, then remove the battery and
set the height of the Trigger by aligning the upper switch in the middle of the larger OD section
of the Trigger and tightening the set screw. Raise the tool head and put the battery back in,
then verify your height by lowering the tool head back onto the case filled with powder; the
alarm should not sound.
Figure 4: Trigger is not aligned with the switch (Left), Trigger is aligned with the switch completing setup (Right).
8. Test the alarm with a case containing no powder and one containing a double charge to ensure
the alarm is working as intended.
9. Run your press normally. The alarm will sound when it detects a nonconforming powder load.
You must check the trigger rod after each alarm and reset it below the switch or it will
continue to sound.
