5-9. Monitoring Voltage and Current
＊
It is possible to monitor the output voltage and current of the
PA-B series in terms of voltages.
1) Shut off the POWER switch.
2) Connect a voltage monitoring meter between the V MONITOR
+ terminal and V MONITOR -(-S) terminal on the rear panel.
Connect a current monitor meter between the I M
terminal and I MONITOR - (-S) terminal.
3) Throw the POWER switch to turn on power.
4) When the output voltage is in the range between 0 V and the
rated voltage, voltage between 0 and approximately 10 V is
output through the V M terminal and V MONITOR
-(-S) terminal.
5) When the output current is in the range between 0 A and the
rated current, voltage between 0 and approximately 10 V is
output through the I MONITOR + terminal and I MONITOR
-(-S) terminal.
NOTE: The V MONITOR - (-S) and I MONITOR - (-S) terminals are
connected together internally. The -S terminal is connected
with the frame GND through the shorting bar. Use the
monitor meters in the floated condition to avoid accidents or
malfunctioning. These monitor terminals may not be used to
observe waveforms.
