21 Cord Reel
This cord reel is used to store the power cord for carrying convenience.
22 Fuse Holder
A 0.3A fuse is used for operating the F L - 1 8 0 on 2 2 0 V or 2 4 0 V A C power. For
operation on 100V or 120V, it should be replaced with a 0.5A fuse.
Note:
Never use a fuse with different current rating.
2 3 Power Connector
A C power connector. Use the supplied A C cord.
2 4 Power Selector Switch
Set this switch to the correct power voltage.
2 5 GND Terminal
Ground terminal.
Note:
Before using, the F L - 1 8 0 must be properly earthed. Improper earthing can
result in electrical shocks.
26 TO S C O P E
A C voltage proportional to w o w flutter is available at this terminal. The output
voltage is about 3V full scale and the output impedance is about 6 0 0 0 . Used
for observing waveforms or analyzing frequencies.
