The meter itself

Measurement modes

The Fluke 233 has quite a few measurement modes:

 Voltage: up to 1000 V. The meter can measure both DC and AC voltages, and is also equipped

with “True RMS”. True RMS means that the effective AC voltage is not only correctly

displayed for sine waves, but also for other waveforms, although there are some limitations

concerning the crest factor of these waveforms.

 Current: up to 10 A, both DC and AC. The current mode is also equipped with True RMS.

Currents between 10 and 20 A can also be measured, but measurements must not take

longer than 30 seconds, and accuracy is not specified for this range.

 Resistance: up to 40 MΩ. Especially handy if you cannot remember those colour codes.

 Temperature: from -40 to 400°C (-40 to 752°F), although the thermocouple must also

support these temperatures. As mentioned above, the included probe can only handle up to

260°C (500°F).

 Capacitance: up to 9999 µF. Especially handy if you cannot decipher those markings.

 Diode tester. For measuring the direction and bias voltage of diodes or transistors.

 Frequency: up to 50 kHz for voltage and up to 5 kHz for current.

 Continuity beeper: indispensable when debugging hand-soldered circuits for shorts. The

display module beeps when a short circuit between the probes is detected.

You can find detailed information about the available ranges and accuracies in the manual. The

specified accuracies are valid for one year after calibration.
