• In resistance measurement, the U3606A will read a non-zero value
even when the two test leads are in direct contact, because of the
resistance of these leads. Use the null function to zero-adjust the
display.
• In DC voltage measurement mode, the thermal effect will influence the
accuracy. Short the test leads and press Null once the displayed value
is stable to zero-adjust the display.
