SOFTWARE

DESCRIPTION

The 1007 is a versatile portable calibrator that can be used for potentiometric voltage measurement in
addition to its operation as a millivolt source. The null zero and sensitivity are adjustable via front panel
controls. Maximum sensitivity enables null balance to resolve 3 microvolt.

• Optional carry case

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 1007 uses a precision reference

diode and low temperature coef cient 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 1007 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 1007 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 1007 in the optional 9027 carry case.

APPLICATIONS

Suitable for calibration and simulation of thermocouples. Accurate voltages equivalent to the output
from a thermocouple can be set quickly and easily on the 1007, enabling fast calibration of temperature
measuring equipment.

Alternatively, the 1007 can measure thermocouples output by operating as a potentiometer. Other
applications include chart recorder calibration, A/D converter and DMM calibration, and use as a stable
voltage for backing off DC offsets.
