ADDITIONAL INFORMATION
DISPLAY UNIT
The display unit is what sets the AmmoMaster ® Chronograph apart
from the competition. The functionality of the AmmoMaster ® display
was designed with the shooter in mind. it allows the user to easily
review statistical data and to review or edit recorded data in memory
at any time during operation. The keypad was also designed with the
appropriate commands necessary to allow the user to step through
any operation with ease. Though data operations are simple to do, we
strongly encourage the user to read through the appropriate sections
in this manual.
1. Depress On/Off button, “rcbs” will display. The unit will, if there is
no previous recorded data, be ready to record shot #1 in string #1.
The unit will display “1” with an indicator shown directly beneath the
“String” header, then disappear and flash with an indicator displayed
directly beneath “Ready” and “Shot” headers (see Figure 13). This
menu informs the user that the unit is ready to record shot velocity
#1 in string #1.
• If unit has recorded velocities from a previous session, please
read Previous Recorded Data section below. if you would like to
remove all previously recorded shot velocities, refer to the Delete
All Data function on the previous page.
