A. INSTALLATION
Select a mounting position that provides full view of DPM and clear of obstructions
using the following mounting instructions.
1. SURFACE CASE MOUNT. i.e. To wall, panel, fan box or over old meter cutout.
Drill 4 ea. Holes per rear view dimensions, 3 ½ x 3 ½”. Secure case with your hardware.
2. Secure AC cord and signal leads to TB1 before mounting.
Then route cord and signal leads through grommets on back or bottom of rear case.
C. OPERATION.
With panel switch to AUTO position DPM will display current duration and hold reading
until next shot is taken.
With AUTO switch to OFF hold function is disabled for checking meter zero and zero
current test.
Zero adjusts are internal, remove case for access.
To calibrate DPM use small screwdriver in ADJ. hole and turn CW to increase or CCW to
decrease meter reading
Standard meters are mean average FWDC calibrated for operation from your existing
50mv/1000 Amp Meter shunt either in place of or in conjunction with your machines
meter. Meters are preset but final calibration depends on accuracy of your existing
meter shunt. An externally accessible adjustment is available for final calibration. They
may be ordered for AC or HWDC equipment and different meter shunt ratings. AC/DC
True RMS meter is also available. Note specifications of full range of options.
Complete with durable die cast case, mounting hardware for panel or surface mount,
meter leads and AC power cord.

AT-23 current meter and shot duration time
meters are for installation on new or old mag
particle equipment to provide the most up
to date accuracy of output amperes and shot
duration with infinite hold, auto reset and
update functions that will meet or exceed all
industrial and military requirements.
High visibility LED digital panel meters
display the output current in amperes and
the duration of output current flow (shot
time) in seconds. Meters hold this reading
indefinitely for accurate recording of each
shot. As each shot is taken the meter will
automatically reset, compute and display the
new readings in less than a second.
