 |
 |
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 a
fast 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 multidirectional
systems.
