Measurement procedure:
- Select DIAGNOSTIC TEST function in MAIN MENU.
- Connect the test leads to the instrument and to the measured object.
- Press the START/STOP key to start the measurement.
- Wait until set timer runs out, the result is displayed.
- Wait until the object under test has discharged
- The result can optionally be saved by pressing the MEM key twice, see the chapter
6.1. Store, Recall and Clear Operation.
Legend of displayed symbols:
Fil0 (Fil1, Fil2, Fil3)
Filter type enabled, see the chapter 5.3.

Notes:
- A high-voltage warning symbol appears on the display during the measurement to
warn the operator of a potentially dangerous test voltage.
- The value of the capacitance is measured during the final discharge of the test
object.
- If enabled, the instrument measures Dielectric Discharge (DD) when the capacitance
is in the range of 5 nF to 50 F.
Setting-up parameters of the Diagnostic Test:
- Press the SELECT key, (the Set-up menu appears
on display, see the Fig. 18).
- Select the parameter to be set using the  and 
keys;
- Adjust the parameter using the  and  keys.
- Complete the set-up adjustments by pressing either
the ESC key or START key (to run the measurement
directly). The settings displayed last are stored.
