Safety Notices

CAUTION

A CAUTION notice denotes a hazard. It calls attention to an

operating procedure, practice, or the like that, if not correctly

performed or adhered to, could result in damage to the

product or loss of important data. Do not proceed beyond a

CAUTION notice until the indicated conditions are fully

understood and met.

WARNING

WARNING notice denotes a hazard. It calls attention to an

operating procedure, practice, or the like that, if not cor-

rectly performed or adhered to, could result in personal

injury or death. Do not proceed beyond a WARNING notice

until the indicated conditions are fully understood and met.

Inductance/Capacitance/Resistance Measurement

Procedure:

1Press the L/C/R key to select inductance (L), capacitance (C), or resistance (R)

measurement.

2Connect the red test clip or SMD tweezers to the +terminal and the black test

clip to the – terminal.

3Connect both the test clips to the component leads as required or use the SMD

tweezers to measure SMD components.

4Press the FREQ key to select the testing frequency.

5Press the D/Q/θ key to select Q or D factor for secondary display as required.

6Ensure that your hands are not touching the clips before taking the readings on

the display.

7The LCR measurements setup are shown in Figure 1- 1 to Figure 1- 1.

CAUTION

Degradation of some product specifications can occur in the presence of ambient

electromagnetic (EM) fields and noise that affects the product’s power line or I/O

cables. The product self-recovers and operates to all specifications when:

•the source of the ambient EM field and noise is removed,

•the product is protected from the ambient EM field, or

•the product cabling is shielded from the ambient EM noise.
