2.5 Turning the Power On and Off
44
No self-test is performed for the Z3003 Multiplexer Unit on startup.
See: "8.6 Performing the Multiplexer Unit Self-test" (p.166)
Before Starting Measurement
To obtain precise measurements, provide about 60 minutes warm-up after turning power
on.
The SOURCE terminal is protected by a fuse. If the fuse is tripped, the instrument will dis-
play “
Blown FUSE.” and you will not be able to measure resistance values. In this case,
replace the fuse.
See: "14.2 Replacing the Measurement Circuit’s Protective Fuse" (p.300)
Measurement settings are recalled from when the power was previously turned off (settings
backup).
Press the Standby key (the Standby key will change from green to red).
Disconnect the power cord from the outlet to extinguish the standby key light.
When power is turned on again, operation resumes with the same state as when last turned
off.
If a power outage (e.g., breaker trip) occurs when the instrument is on, it will automatically
turn on again when power is restored (without pressing the standby key).
Self-test
Indicates an error (p. 296).
After the standby state is canceled, a self-test (instrument diagnostic routine) is performed.
During the self-test, the following information is displayed while the hardware is verified.
