Basic Measuring
3.7.2 Trigger Delay
Set the trigger delay time, and such function is normally used by the automated
equipment.
Caution ：
The trigger delay time is set as 0-5000mS. If exceeding the high limit
value, it will be adjusted back to 5000mS by the system
automatically.
3.7.3
Output impedance
The “100Ω” or “25Ω” can be selected according to the user’s demand. The varied
signal source output impedance will lead to the varied current or the difference of
measuring value
3.7.4
ALC
It is preset as “Off”. If selecting “On”, it ensures that the voltage applied to both
ends of Test Piece or the current flowing through the Test Piece will be consistent
with the parameter set value. If selecting “On”, because the instrument needs to
calculate the voltage and the current for adjusting the output, it will increase the
time required for the measuring. If the Auto Potential Control cannot achieve the
range to be set, the page will display “AC ALC FAIL” message.
3.7.5 AC/DC Delay
If AC parameter and RDC are included in the measuring, it can set the delay time
between AC/DC measuring. This function is also suitable for when the measuring
value of the Test Piece between AC/DC is instable.
3.7.6 Average
If the measuring value is instable, the average measuring count can be set within
1-64 times. The higher the average count, the steady the measuring value; on the
contrary, the slower the measuring speed.
