3.5 Features
Model 5406A has the follwing features:
Battery is not used Model 5406A is not battery-operated, but operates
by the voltage supplied from the system.
Wiring check Three LEDs indicate if the wiring of the circuit
under test is correct.
Over temperature Detects overheating of the internal resistor and of
the current control MOS FET displaying a warning
symbol ( ) and automatically halting further
measurements.
Phase angle selector The test can be selected from either the positive
(0
。
) or from the negative (180
。
) half-cycle of
voltage. At those two points, tests minimum (best)
and maximum (worst) trip times.
Auto data hold Holds the displayed reading for a time after the
test is complete.
UL value selector Select UL (limit of touch voltage value) 25V or
50V. Where Uf (fault voltage) exceeds UL value,
"Uf Hi" will be displayed without starting the
measurement.
Optional Accessory Model 7121 distribution board or lighting circuit
test lead.
