6.6 Ending Measurement
Press the [STOP] key when finishing measurement.
Pressing the [STOP] key lights up the [STOP] lamp beside the key. Trigger input will be
prohibited.
When the dedicated power supply unit PSU
- 8541 is connected, the measuring voltage
output will become “0V” in a [STOP] condition.
The circuit between the “OUTPUT” terminal and “INPUT” terminal will become a
discharge state (discharge state with a current limiter connected).
If an external power source that cannot be controlled by the meter is connected, the
voltage output will be decided by the condition of the external power device. Be
cautious about an electric shock in this case.
[Warning]
Residual measuring voltage sometimes still remains inside the sample after
pressing the [STOP] key. Be cautious and do not touch metal parts
impressed with voltage till the inside of the meter is thoroughly discharged.
Otherwise an electric shock may result.
[Warming]
If the dedicated power supply unit is not used, measuring voltage may
continuously be output to the sample after pressing the [STOP] key.
Be cautious and do not touch metal parts impressed with voltage till the
inside of the meter is thoroughly discharged.
6.7 Measurement
Check
The meter is capable of checking “acceptable” or “non-acceptable” of a measured state
as explained below.
6.7.1 Voltage
check
The voltage check function checks output state of measuring voltage and determines if
measuring voltage is output normally. The voltage check accuracy is ±3% and the
setting accuracy of measuring voltage cannot be checked. The voltage check function
is mainly used in detecting flaws of the voltage output circuit and operational state of
current limiters.
If the measuring voltage is below 10V, correct decisions sometimes cannot be made due
to voltage check accuracy problems. Use this function when the measuring voltage is
higher than 10V.
Voltage checks can be made for each measurement and only when necessary by
operating the panel keys or by issuing commands through interfaces.
[Notice]
Measurement and data output will be made as in normal operation even if a
decision of voltage check is <NG>. However, signals will not be saved in
the data buffer if the result of a voltage check is <NG>.
