5.2.9 Creating a program
A program can be set for sequential measurement that will be useful when the time for
impressing measuring voltage accurately to the sample needs be controlled accurately.
Sequential measurement presets the following items and enables inspection under the
same conditions.
(1) Discharge 1: Set a discharging time before impressing voltage.
(2) Charge: Set a time for impressing voltage before starting measurement.
(3) Measurement: Set a time for measurement.
Measured values after these set times are output.
(4) Discharge 2: Set a discharging time after finishing measurement.
These four values are displayed on the Measurement screen together with a program No.
[Warning]
Residual measuring voltage sometimes still remains inside the sample after
measurement is finished when high voltage is impressed in manual measurement.
Removal of a sample immediately after measurement is hazardous as there is a
risk for an electrical shock. Set a time for Discharge 2 and remove a sample after
hazardous voltage is thoroughly discharged.
[Notices]
1. When shut down, the DSM-8542 is always in a discharge state. Set Discharge
1 when necessary taking the jig and scanner that have contacted the outside
into consideration. Discharge 1 is almost irrelevant when the DSM-8542 is
used independently.
2. The state between the measuring input terminal and [OUTPUT] terminal in a
discharging condition (also during a shutdown) is the one to which a circuit that
has a set current limiter and input resistance (about 1k
Ω
) of the current
measuring unit in series is connected.
Set the sequence program as follows.
First, set the Sequential Measurement Monitoring screen.
