4.9 Setting the Contact Check
4-41 ZM2376
4.9 Setting the Contact Check
ZM2376 provides the contact check function which can check the contact condition with DUT. To
avoid a wrong measurement due to contact failure, set the contact check to “enabled”.
ZM2376 also provides the low capacitance check function to detect an abnormal low capacitance
caused by a contact failure, independently of the contact check function described above.
The contact check and low capacitance check provided by ZM2376 do not give an additional error to
measured values. An additional time to the measurement can be ignored.
