4.5 Setting the Delay Time for Measurement (Delay Function)
This function adjusts the time for measurement to stabilize by inserting a
waiting period after use of the OVC or the auto range function to change the
measurement current. When this function is used, the instrument waits for its
internal circuitry to stabilize before starting measurement, even if the
measurement target has a high reactance component.
The PrSEt (preset value) depends on the range used and the offset voltage
compensation function.

IMPORTANT
l When the offset voltage compensation function is ON (the OVC
indicator is lit), the measured value will be slow to refresh.
l The OVC function cannot be used in the 3kΩ range or higher. The
function is automatically turned OFF.
l When the offset voltage compensation function is changed, the zero
adjustment function is cancelled.
l When the measurement target has a high inductance, it is necessary to
adjust the delay time.
l
Start with a longer delay time than necessary, and decrease the time
gradually, watching the measured value.
l If the measurement target has a low heat capacity, the offset voltage
compensation function may have no effect.
