1030 Voltage and Current Source

The 1030 MicroCal is a portable voltage and current calibrator for general purpose signal injection. It is suitable for voltage and current loop signal simulation as well as thermocouple simulation. With fast analogue setting,  it is a popular engineers field calibrator used in various applications. 

Three voltage ranges give an adjustable output from 10 μV to 1 V and two current ranges for 10 μA to 100 mA. An additional 0 to 8 V output can be obtained by using the 1 KΩ resistor that is supplied with the unit. It can be connected across the output terminals and the 10 mA current range selected. It allows the output to be set between 0 and +/- 8 V with a 10 mV resolution and an accuracy of 0.3 % of full scale. 

The 1030 is simple to operate and does not require any standardisation prior to use. The operator needs only to switch on, check the battery condition, and set the required range and output value. The unit is a pocket-sized, practical test tool for technicians requiring a precision compact solution for low range DC V/I sourcing.

Portable Calibrator

Portable and Practical

The compact (115 x 62 x 55 mm) and durable design makes it ideal for use in the field, with carry case supplied as standard.

Typically battery life is 60 hours depending on usage. An optional rechargeable battery pack is available, with mains charger that connects via a socket on the top of the unit.

Analogue Control

Quick and Easy Analogue Control

The 1030 is designed for traditional and quick analogue control. Range selection is simple via the front panel switch and output setting is made using a precision 10-turn dial. 

This control provides a conventional feel to selecting the required voltage or current, with a setting resolution of 1 part in a 1000 (0.1 %).

1030 Applications

Accurate measurements of low ohm values, such as platinum resistance thermometers, can be performed by using the 1030 as a current source and measuring the voltage across the load with a digital voltmeter.

The 10 mV range is ideal for simulation of all types of thermocouple. For checking and calibration of meters, the 1030 can be used to provide the necessary voltage or current to perform testing applications.
