1006 DC Millivolt Source

The 1006 is an accurate millivolt source suitable for voltage injection applications. Three output ranges are provided to give adjustable output values from 1 μV to 1 V with a basic 0.02 % accuracy. 

For signal injection, the operator needs to switch on, check the battery condition, select the range, and set the required voltage using the thumbwheel switches. The instrument uses a precision reference diode and low temperature coefficient resistors to give a highly stable output.

Power is provided by 6 AA batteries. Battery life is several months, depending on usage. The battery condition is monitored by an indicator situated on the top of the unit.

The 1006 has up to 20 mA drive current and is short circuit and overload protected. An off/normal/reverse output polarity switch is provided.

Safety Terminals

Safety Terminals

The 1006 connections are via safety terminals that are compatible with standard plugs, 4 mm shrouded plugs, bare wires, and spade terminals. 

These terminals are specifically designed with safety features including limited opening distance and a raised flange around the metal connection surface. This ensures that the clearances are sufficient to make the exposed metal parts touch-proof.

1006 Protective Boot

Added Protection

The 1006 DC mV source comes fitted with an ergonomic rubber cover providing increased protection and durability. It has a textured grip for comfortable handling and a top opening for access to the battery level indicator and cell compartments.

It is easy to remove if the user prefers a stand-alone unit or to house the instrument in the optional 9026 carry case.

1006 Applications

As an accurate millivolt source, the 1006 can be used for many applications including thermocouple simulation, chart recorder calibration, A/D converter calibration, and as a stable voltage for backing off DC offsets.

The instrument is robust and portable for field applications. It can be utilised in R&D applications as a dedicated stable voltage source, or used for calibration of test tools and instrumentation like voltmeters that measure DC voltage.
