Resistance Measurement (Ω) - Omega CA450 User Manual

DC SENSOR range
) Connect the sensor that you will use to the input terminals.
) Read the value when it stabilizes.
To return to normal mV measurement, press SHIFT+SELECT again.
Example of measurement when connecting a current clamp sensor with an input-to-output ratio
of 0 mV/A
Use the setup function (see section 4.6) to configure the following settings.
Instrument input voltage: 0.0 (mV)
Converted value, decimal place: 0.00
Unit: A
If you connect the sensor after configuring the above settings, the current clamp sensor'
s output voltage (in mV) appears in the subdisplay, and the current detected by the current
clamp sensor appears in the main display. (You can read the values directly.)
4.3.4 Resistance Measurement (Ω)
CAUTION
To avoid damaging the instrument:
Before measurement, turn off the circuit under measurement so that no voltage is
applied.
1) Turn the function switch to the "Ω" position.
2) Insert the test leads into the input terminals.
) Connect the test leads to the circuit under measurement, and
then read the value when it stabilizes.
