When measuring energy storage devices (e.g. capacitors, inductors) on the LCR/ESR meter or some of the other meters, it is IMPORTANT to discharge them before connecting them to the meter as the release of energy into the meter may seriously damage the meter.
Which buttons are used to set the primary and secondary displays on the LCR/ESR meter?
In order to measure the parasitic resistance (series resistance) of an capacitor using the LCR meter in the diagram below, what sequence of actions must be performed to facilitate measurement?
i. Ensure that the appropriate cables are connected to the LCUR LPOT HCUR HPOT terminals.
ii. Power on the LCR/ESR meter.
iii. Press and release L/C/Z/DCR Function key a few times until the primary display turns to Cp.
iv. Press and release L/C/Z/DCR Function key a few times until the primary display turns to Cs.
v. Press and release D/Q/θ/ESR Function key a few times until the secondary display turns to ESR.
vi. Press and release D/Q/θ/ESR Function key a few times until the secondary display turns to D.
vii. Attach the clips to the end of the device that is to be measured.
