Notes:

=

Peak to peak. The threshold can be factory set to provide optimum performance over a specific band of interest.

>

The alarm threshold is proportionate to IEEE C95.1-1991 Standard and varies over the 2 to 30 MHz band. The threshold is 0.9% of

the H field Maximum Permissable Exposure (MPE) from 3 to 30 MHz and equal to 10% of the E field MPE from 2 to 30 Mhz.

(Controlled Environments)

?

The 3 dB intercept angle is >180

°

with the E field tangential to the mounting plane and >165

°

with the E field perpendicular to the

mounting plane.

@

The rated life is two years. It is recommended that this battery be replaced annually during calibration.

A

The fail-safe battery has a rated life of 5 to 10 years. It is recommended that it be checked annually during calibration and replaced

every three years.

B

Other calibration frequencies available for narrow band applications. Contact the factory.

Notes:



The STATUS signal available at J1 is a voltage source that

provides >2.4 Vdc into a 500 k

load when “High.”

The voltage drops to <0.8 Vdc when ”Low.” The load

impedance can be reduced to 24 k

providing that

the Main Battery Failure signal is not required.

Jack type is 3.5mm miniature phone.

J2 Input: Normal condition is an open circuit.

A short circuit (<100 ohms) disables the SMARTS.

Jack type is 2.5 mm miniature phone.
