THE new Picotest M3500A six and a half digit DMM with USB port and optional 10 channel scanner card from Westek Electronics Pty Ltd is suited to R&D, scientific as well production and service tasks.
The Picotest M3500A measures AC and DC voltage, DC and AC current, resistance and temperature for E, J, K, N, R, S and T thermocouples. The instrument is provided with 5x7 dot-matrix, two-line, colour-coded display and with a USB port permitting data transfer rates of up to 2000 readings per second.
MatLab and LabView software permit the user to carry out a large variety of tasks. The Picotest M3500A is characterised by high accuracy and stability providing, for example, a voltage accuracy over a 24 hour period of (0.0015% of reading.
Voltage is measured to 1000 V DC (750 V AC), current to 3 amps AC/DC, resistance to 100 megohm, and frequency/period to 300 kHz. Options include a GPIB interface card, thermal adapter for thermocouples and an RTD probe adaptor.
