Description
| For industrial or commercial applications,
the Round style panel meter offers maximum reliability and ±2%
full scale (F.S.) accuracy for iron-vane movements, and ±3%
for rectifier types. With a black phenolic case and glass window
for optimum viewing, the Round style meter is a popular selection
for industrial applications because the cover extends to the back
of the case. AC units have either iron-vane type or rectifier type
movements and are calibrated at 60Hz. Ironvane type current meters
have a frequency range of 25 to 800Hz (for ±1% deviation
from value at 60Hz). All rectifier types have a 25Hz to 10KHz range.
Two different standard sizes of 2-1/2" and 3-1/2" are
available to measure various current ranges. This style meter is
ideal for many other electrical functions. |
