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.

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.
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.
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.
0 to 999.9 mV in 3 ranges:
1 V range: 0 to 999.9 mV in 0.1 mV steps
100 mV range: 0 to 99.99 mV in 10 μV steps
10 mV range: 0 to 9.999 mV in 1 μV steps
± (0.02 % of setting + 0.02 % of range + 1 μV)
Less than 0.2 Ω on 1 V and 100 mV ranges. 1 Ω on 10 mV range.
Maximum Output Current
1 V and 100 mV ranges: 20 mA. 10 mV range: Up to short circuit value although it should be noted that loads of less than 1 kΩ will give greater than 0.1 % error.
Output Voltage Stability
Less than 60 ppm/°C. Less than 100 ppm per 3 months (non-cumulative).
Positive or negative switch selected. A centre ‘off’ position is also provided.
Output Noise Level
Less than 30 ppm of full scale.
Precision bandgap reference diode, for stability and low temperature coefficient.
The instrument can withstand continuous short circuit on the output for all ranges.
6-AA size (51 x 14 mm) batteries. A battery level indicator shows when the batteries should be changed.
An alternative power source is 6 NiMH cells of the same dimensions. These can be recharged via a socket on the top of the unit. The 6 rechargeable batteries and mains recharger are available as an optional extra.
