ATS-20B AMMETER & TIMER CALIBRATION METER PANEL CONTROLS

 

Model ATS-20B is a complete portable current Ammeter, Duration (Shot) time meter with a removable Meter shunt built into a durable abs storage case.Certified to NIST standards to meet or exceed international industrial and military MPI equipment calibration requirements. It will measure AC, FWDC and HWDC current in the Mean Average, True RMS or Peak detection methods in less than 300msec up to 20,000 amperes. It has auto hold for storing last reading indefinitely with automatic reset and update after each measurement or may be operated in manual mode.Duration (Shot) Time is automatic and measures current flow up to 20 seconds.

AMS-21 AMMETER & SHUNT CALIBRATION STANDARD
 



The Model AMS-21 is a complete high current Digital Ammeter and removable Meter Shunt built into a durable ABS storage case.Certified to NIST standards that meet or exceed international industry and military meter calibration requirements. Will measure an AC, FWDC or HWDC with afast 300msec response time. It has auto hold for storing last reading indefinitely with automatic reset and update after each measurement or may be operated in manual mode. Standard averaging meters may be calibrated to only one type of signal input. Ideal for FWDC systems. Select your choice of FWDC, HWDC or AC when ordering.True RMS meters will measure AC, FWDC or HWDC. Ideal for AC/DC and multi directional systems.

OPERATION

 

1. AT-25 Power Switch to ON. DPM will display any random number when power is firstapplied. Press Manual reset and DPM will display 0.00 ± .01.

2. With test leads plugged into AT-25 panel jacks, clip one lead each to copper pad or late of head and tail stock, or on coils, clip one lead each to input and output buss bar or lug nut from coil of MPI equipment under test. Parts should be removed from between Head andTail stock.

3. Operate MPI equipment at your normal output current setting. You may have to increaseoutput current setting when monitoring coil shots to start AT-25 Timer.

4. AT-25 will display your shot time until your next shot is taken. Allow 1 second between shottimes for automatic reset. You do not need to press manual reset between shots.

5. Quick Break Tester will monitor Fall Time automatically. Green OK LED or Red N.G. LED willremain lighted after shot has ended to indicate a Passed or Failed Quick Break Test.

6. Manual Time runs while push button is pressed, stops when released.

7. Manual reset zeros DPM when push button is pressed.

8. AT-25 input is bipolar. Input leads can be reversed.
