Instruction manual

2. Either open or short calibration is not

associated with measurement function,

therefore changing the test function does not

require re-calibration.

3. Re-calibration may be necessary depending

on many factors such as prolonged use,

changing environments, and contact variation

(i.e. alligator test leads or socket contacts).

USB

The USB button (or for model 878B) are

used for remote communication. See “REMOTE

COMMUNICATION” section for details.

Automatic Fuse Detection

The LCR meter has an internal fuse that protects the

inputs from severely damaging the instrument. When

the meter detects that the protective fuse is open, the

“FUSE” indicator will appear on the primary display

(see Figure 9) and an internal “beep” will sound

continuously. In this situation, none of the function

buttons can be operated and all other meter functions

will be disabled.
