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.

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 1007 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 1007 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: Fitted as standard and fully compatible with 4 mm

shrouded plugs, as well as standard plugs, bare wires, and spade terminals.

Added Protection: The 1007 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 indicator 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 multimeter calibration, and use as a stable voltage for

backing off DC offsets.
