7.0 to 40 Volts, 2/10 Amp
Viewable in direct sunlight, with dimmable 12 and 24 volt backlight control lines.
1% of reading +/- one count.
VA-1A and VA-1A-XX (60 Amps and below for "XX") resolve amperage
to .1 amps. VA-1A-XX (above 60 for "XX") resolve to 1 amps. All units resolve voltage to .1 volts.
Contains an internal shunt for measuring current to 100 amps and
voltage to 40 volts.
This unit must be matched to the aircraft's external shunt. The
shunt value is determined by how many amps must pass through the external shunt in order to acheive a 50mV drop across the
shunt leads (i.e., 100 amp, 50mV external shunt would be matched to a VA-1A-100, a 70 amp, 50mV external shunt would be
matched to a VA-1A-70, etc...).
