1006 DC Millivolt Source

1006 DC Millivolt Source

Product Description:

The 1006 is an accurate low cost millivolt source suitable for voltage injection applications. Three output ranges are provided to give adjustable output values from 1µV to 1V 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 1006 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 mounted on the top of the unit. The 1006 has up to 20mA drive current and is short circuit and overload protected. An off/normal/reverse output polarity switch is provided.

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 1006 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 1006 in the 9027 carry case.

Applications

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

The 1006 is an easy to use calibration instrument designed for accuracy and reliability. As part of the Time Electronics portable test equipment range it is ideal for use in the lab or field.

Technical Specification:

Output 0 to 999.9mV in 3 ranges:

0 to 999.9mV in 0.1mV steps

0 to 99.99mV in 10μV steps

0 to 9.999mV in 1μV steps

Accuracy            ± 0.02% of setting + ± 0.02% of range + ± 1µV.

Output Resistance         Less than 0.2Ω on 1 V and 100 mV ranges. 1Ω on 10mV range.

Maximum Output Current          1V and 100mV ranges = 20mA. 10mV range = Up to short circuit value although it should be noted that loads of less than 1kΩ will give greater than 0.1% error.

Output Voltage Stability              Less than 60ppm/°C.  Less than 100ppm per 3 months (non-cumulative).

Output Polarity Positive or negative switch selected.  A centre ‘off’ position is also provided.

Output Noise Level        Less than 30ppm of full scale

Reference Source           Precision zener diode, selected for stability and low temperature coefficient.

Maximum Overload      The instrument can withstand continuous short circuit on the output for all ranges.

Power Supply    6-AA size (51x14mm) batteries. A battery condition display indicates 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.
