Function Descriptions
1. Parameters setting
Press FUNC. key to select the following parameters sequentially: AUTO LCR, L-Q, C-D, R, DCR.
L/C/R measurement readings can be positive or negative. In C-D measurement, if the main parameter is "-", the actual
component being tested is inductive; In L - Q measurement, if the main parameter is "-", the actual component being tested is
capacitive; Theoretically, R is positive, in some cases, R is "-" , which may be calibration error, please re-calibrate the
instrument.
2. Auto LCR smart mode
The default test mode is Auto LCR mode which could check the type of impedance smartly.
If |θ|<11°, the Auto-R mode is selected. The parameter on sub-display is θ.
