One common application is to increase the accuracy
of a small resistance measurement by storing (nulling)
the test lead resistance (test leads shorted).
Obtaining the leads offset (nulling) is also particularly important
prior to making small capacitance measurements (test leads open).
Smart Tweezers allows to store measurement
offset for L, C, R component separately.
To store an offset
•
Select manual L, C or R measurement mode (see MODE menu)
•
Enable the HOLD mode (see HOLD menu)
•
Obtain offset value by measuring a component or
by nulling test leads (see examples below)
•
Enter the NULL menu and select SET
Example 1:
Nulling test leads for small resistance measurement
• Select manual R measurement mode (see MODE menu)
• Enable the HOLD mode (see HOLD menu)
• Short tweezers leads to obtain offset value
• Enter the NULL menu and select SET
Example 2:
Nulling test leads for small capacitance measurement
• Select manual C measurement mode (see MODE menu) and 10KHz
test frequency (see SETTINGS menu)
• Enable the HOLD mode (see HOLD menu)
• Bring tweezers leads to the distance equal to
the size of the component to measure (e.g. 0.5
mm) to obtain capacitance offset value
• Enter the NULL menu and select SET
