Aim-TTi 1604 4� Digit Low-Cost Bench Digital Multimeter

A value-for-money DMM

The 1604 is a low-cost auto/manual ranging bench-top DMM with a large and bright LED display. It offers 4¾ digit (40,000 count) scale length, true RMS ac measurements, a basic accuracy of 0.08% and a resolution of 10µV, 10mOhms and 0.1µA.

A substantial bench-top instrument

The 1604 is a robust mains-powered bench-top instrument. Unlike a hand-held multimeter it stays where you put it even with heavy test leads connected. The multi-position tilt stand ensures that the large display is always readable.

Smart functions

The 1604 incorporates several “smart” functions such as Relative measurement and Minimum-Maximum storage. The T-Hold function enables readings to be held on the display automatically each time a new test point is probed.

True RMS ac ranges

All AC measurements on the 1604 are True RMS. This avoids the errors on non-sinusoidal waveforms associated with other multimeters. Good ac bandwidth enables measurement within the audio band and ensures that higher frequency components of switching waveforms are included within the measurement result.

Frequency measurement

The 1604 has a frequency function which can be selected on any ac range in order to measure the frequency of the signal. Frequencies up to 40kHz can be measured and the maximum resolution is 0.1Hz.
Isolated RS-232 interface

The 1604 is fitted with an isolated RS-232 interface. This permits remote control and data-logging to disk using optional Windows based software.
