Digital Mulitmeters

| Posted in Test Equipment

In the shack I have two digital multimeters, both being manufactured by Fluke.

Fluke 77 digital multimeter
At first glance the Fluke 73 meter (on the left) may appear to be a basic unit. However the meter is fully auto-ranging, meaning that it automatically adjusts to the correct measuring range of the measurement being taken.

Due to damage, the plastic LCD protection screen has been replaced by a piece of clear perspex. While not affecting the accuracy and operation of the meter, it makes the overall appearance of the instrument plain.

This meter can handle AC or DC volts, current (amps), resistance and diode testing. Also included is Fluke’s patented TouchHold® mode which automatically captures the measurement, beeps, and locks it on the digital display for later viewing.

This handy feature makes taking a reading without having to look at the meter a piece of cake.

Fluke-8060A digital multimeter
The Fluke 8060A is a more complex instrument than the Fluke 73 meter.
It can handle all the measurements that the Fluke 73 makes, with additional functions such as, frequency measurement up to 200KHz, dBm or relative dB measurements, offset (relative) reference and conductance
measurements.

Measurements are also taken using a True RMS system, this makes it more accurate when making AC measurements.
