1. INTRODUCTION Automatically records up to 16,000 (!) data points in the field along with time and date. These can later be downloaded to a computer via the meter’s RS232 port and the results viewed instantly on software which comes with the unit. The software also enables real time data logging directly from the meter to the computer.
