SOFTWARE

DESCRIPTION

A multi-purpose handheld test instrument that can be used as an adjustable current load, adjustable power
supply, or precision current source. The 1077 is commonly used for the testing and simulation of milliamp
transducer systems. Compact and rugged design make the 1077 ideal for use in both the lab and eld.
With a protective rubber cover to increase durability, the instrument can withstand arduous use and is well
suited to process control applications.

• Optional carry case

Three Operating Modes:

1) As an adjustable current load (simulating the transducer) on the line, the 1077 will draw up to 100mA from
the line. The required current is set by the front panel controls.

2) As an adjustable power supply (14V to 40V) with accurate measurement and display of the current drawn
from the circuit.

3) As a precision current source with 14V to 40V maximum (adjustable) drive capacity. The 1077 will source
the set current up to 100mA to the loop.

Safety Terminals: Fitted as standard and fully compatible with 4mm shrouded plugs, as well as standard

plugs, bare wires, and spade terminals.

Added Protection: The 1077 comes tted with an ergonomic rubber cover providing increased protection

and durability. It has a textured grip for comfortable handling and openings at the top and bottom to allow
access to the battery meter and a position to place labels if required. It is easy to remove if the user prefers
a stand-alone unit or to house the 1077 in the optional 9027 carry case.

PORTABLE OPERATION

Rechargeable batteries and mains charger are supplied with the unit as standard.

Complete recharge time is 10 to 12 hours although sufcient charge for a few hours

operation can be obtained with only 30 minutes charge. Full charge allows 10 hours
typical use. The battery condition monitored by a meter on the top of the 1077.
