GENERAL SPECIFICATIONS

Connection: 2 mm (0.08") diameter test plugs

Housing material: ABS resin

Mode switch: Switchable between 2-wire loop mode and 4-

wire mode

The 2-wire loop mode controls current signals supplied from

the power source such as a current loop supply, to perform

a loop test (sink capability), whereas in the 4-wire mode,

constant current is supplied to the transmitter

(source capability).

Output range: 0 – 24 mA DC

Output monitoring: Directly measure output current

Monitor jack: 2 mm (0.08") diameter

Power LED: Red LED turns on when the power is supplied.

Continuous operating hours: Approx. seven hours with load

resistance 750 Ω, output 12 mA, and when three new

alkaline AA cells are used.

Usage: Stand ot strap holder
