3.2 Starting a Test
40
Carry out the test after finishing setting the test conditions (p. 31).
For safety reasons, key lock is recommended. All keys except the START key
and STOP key are disabled while the key-lock function is active. (p. 79)
3.2 Starting a Test
To prevent electric shock, check the following before starting test.
Front panel
•The DANGER lamp is
OFF.
• The lamp is lit
(it is off in the Double
Action mode).
• When the tested object in use shows dependency on voltage (impedance of
ceramic condenser, etc.), the waveforms of the output voltage may become
distorted. The tested object may malfunction depending on the distortion of the
waveforms.
• Continuous output of a high voltage may heat the bottom of the instrument.
To
prevent from getting scalded, do not touch the bottom.
• There is a priority hierarchy for the START keys.
Priority hierarchy: Remote Control Box > EXT I/O > Front panel of the 3174
(3174-01)
Note that when a START key with a higher priority is in use, lower-priority
keys are disabled.
• When the tested object in use possesses an inductivity like a coil, a voltage
higher than the pre-set voltage may appear transitionally, causing damage in
the tested object.
• The tested object may damage if a voltage higher than necessary is supplied.
Be careful when setting the output voltage to ensure that the tested object
does not receive a voltage higher than necessary.
• The tested object may damage if a voltage is supplied longer than necessary.
Be careful when setting the test time.
