Product Details

Aim-TTi 1908 Series Dual Measurement Bench Multimeter

Aim-TTi 1908 Series is a dual measurement, dual display bench-top/portable multimeter. It features continuity and diode test, automatic or manual ranging, linear scaling with offset, dB measurements, limits comparison, percentage deviation (%), min-max storage, power measurement in watts or VA, automatic data logging and external triggering. The logger function can store up to 500 readings from the main display in non-volatile memory. The two displays can be used to display a measurement along with the selected range (e.g. 100 Vdc), a measurement in two different units (e.g. AC volts and dBm), the result of a calculated function (e.g. value and % deviation), two parameters of one signal (e.g. AC and DC volts) or two different signals (e.g. AC volts and DC current). Software 1908-PC Link provides remote control of main functions and logging function with graphical and tabular displays (logged data can be exported to a CSV file). Model 1908P can be remotely controlled via its RS232, USB, GPIB or LAN interface. Model 1908 (non ’P’) can only be controlled via USB.

In dual measurement mode a completely independent but complementary measurement can be made and displayed on the secondary display. The two independent measurements are made alternately, not simultaneously, and the display update rate for each measurement is consequently reduced (this is not the same as dual display mode, where both a measurement and a modified version of that measurement are displayed e.g. ac Volts and the dB equivalent).
