Product 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 field, with protective rubber cover to increase durability. The instrument is built to withstand arduous use, meaning it is well suited to process control applications.
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. It 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 fitted 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 sufficient 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.
