7) Connect the voltmeter to [INPUT Ch1 MONITOR] as it is. Record the measured
AC voltage.
8) Change the connection of [OUTPUT Ch1] to [INPUT Ch2] of the I/O UNIT. Also
change the input setting of K2 to Ch.2 from Ch.1. The input sensitivity of Ch.2 is
the same as Ch.1.
9) Operate the same procedure as 3) ～ 7) and record the measured data.
10) These procedures are also needed to be operated for Ch.3 and Ch.4. When the
optional input channels are added, the input channels Ch1. ~ Ch8 of the expansion
board are also needed to be measured and recorded.
＜ Charge input sensitivity test ＞
Connection of the instruments
Connect the equipment by the cables as in the same way as in the system of
<Voltage input sensitivity test / monitoring output test> above. Also connect [INPUT
Ch1] of the I/O input to the capacitor.
Operate the performance check
1) Record the capacitance of the used capacitor and calculate the input voltage by the
equation.
C : Capacitance [pF]
V : Input voltage [mVrms]
V = 1000 ÷ C × 353.5
Example) Input voltage 354.4mV is obtained when the capacitance of the used
capacitor is 997.4pF.
2) Select the manual operation.
