  • The 1030 MicroCal is a portable voltage and current calibrator for general purpose signal injection. As part of our portable test equipment range, it is suitable for voltage and current loop signal simulation as well as thermocouple simulation. 

    Being both cost-effective and simple operation make the 1030 a popular instrument that is used in various applications across industries. The compact (115 x 62 x 55mm) and durable design makes it ideal for use in both the lab and field, with carry case supplied as standard. Typical battery life is 60 hours. An optional rechargeable battery pack is available, with mains charger that connects via a socket on the top of the unit. 

    The MicroCal is designed for traditional analogue control. The precision 10-turn dial provides a conventional feel to selecting the required output with a setting resolution of 1 part in a 1000 (0.1%).

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

    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 10mV range is ideal for simulation of all types of thermocouple.

    The 1030 is a compact calibration tool, ideal for electrical engineers to test various measurement equipment, temperature controllers, and PLC analog input cards, with mV or mA inputs. As with all models in the Time Electronics handheld calibrator range it is designed for accuracy and reliability, whilst maintaining ease of use.
