Operation Manual
TeraOhm 5kV
23
Notes:
- A high-voltage warning symbol appears on the display during the measurement to
warn the operator of a possible dangerous test voltage.
- The value of capacitance is measured during the final discharge of the measured
object.
- If enabled, the instrument measures DD when the measured capacitance is in the
range of 5 nF to 50
μF.
Set-up parameters for Diagnostic Test:
- Press the SELECT key, Set-up menu appears on
display, see the figure 12.
- Select parameter (line) to be set using the ↑ and ↓
keys;
- Adjust set parameter using the ← and → keys.
- Complete the set-up adjustments pressing either the
ESC key or START key (to run the measurement
directly) or changing the rotary switch position. Last
displayed settings are stored.
