Capacitance Measurement; Low Z Measurement (Elimination Of Interference And Induced Voltages) - Sonel CMP-200F Manual De Uso

5.7 Capacitance measurement

WARNING
Risk of electric shock. Disconnect the power supply
from the tested capacitor and discharge all capacitors
before any starting capacity measurements.
To perform the measurement:
 set the rotary switch at Ω
 connect black test lead to COM terminal, and red test lead to
VΩ CAP terminal,
 press MODE button to display F on the screen,
 contact the probe tips to the tested capacitor,
 read the measurement result on the display.
5.8 Low Z measurement (elimination of interference
and induced voltages)
Measurement function in 'Low Z' mode eliminates the influence
of interference voltages or induced voltages, making the measure-
ment more accurate and reliable. These voltages may occur due to
capacitive coupling between the live conductors and the unused
conductors located in the vicinity.
To perform the measurement:
 set the rotary switch at V
 press MODE button to display the following symbol:

, if an alternating voltage is to be measured,

, if a constant voltage is to be measured,
 connect black test lead to COM terminal, and red test lead to
VΩ CAP,
 contact probe blades to measurement points (for DC circuits:
connect red probe to the positive pole),
 read the measurement result on the display.
