Rotation Speed (Rpm); Temperature And Resistance - AEMC 8220 User Manual

4.6.5

Rotation Speed (RPM)

This mode requires the Model 8220 to be pre-configured (refer to § 4.5).
In this position, the Model 8220 measures the rotation speed of a turning ele-
ment.
NOTE: The tachometer signal should be applied into the voltage (+) and (COM)
terminals of the Model 8220. The unit then measures the interval of time be-
tween each signal pulse (event) and subtracts the rotation speed in revolutions
per minute.
4.6.6

Temperature and Resistance

In this position, the Model 8220 measures the temperature (using an external
probe not provided) or the resistance of an electrical circuit.
First Function: TEMPERATURE MODE
The Model 8220 displays the temperature measured using a 100 platinum probe
(not provided), connected to the (+) and (COM) terminals. The measurement is
displayed simultaneously in degrees Celsius (°C) and degrees Fahrenheit (°F).
Second Function: RESISTANCE MODE
Two automatic ranges are available:
• 0 to 400Ω: under 20Ω (by default) a beeping sound is emitted
• 400 to 2000Ω
