Preparations for Measurements
Turning ON/OFF the Power Switch
Items to Be Checked before Turning ON the Power
• Check that the instrument is properly installed. See section 3.2.
• Check that the power cord is properly connected. See the previous page.
Turning ON/OFF the Power Switch
Pressing the power switch located on the left side panel to the “ON (|)” side, turns the
power ON. Pressing it to the “OFF (O)” side turns the power OFF.
Power Up Operation
When the power switch is turned on, self testing and calibration start automatically. This
lasts for approximately 30 seconds. When the SL1400 starts normally, the waveform
display screen appears. Check that the SL1400 has started normally before you use it.
If the SL1400 Does Not Start Normally When the Power Is Turned On
Turn off the power switch, and check the following items.
• Check that the power cord is securely connected.
• Check that the correct voltage is coming to the power outlet, see the previous page.
• Initialize the settings to their factory defaults by turning on the power switch while
holding down the RESET key. For details about initializing the settings, see section 4.4.
If the instrument still does not work properly, contact your nearest YOKOGAWA dealer
for repairs.
Note
•
After turning the power off, wait at least 10 seconds before you turn it on again.
•
It takes several seconds for the startup screen to appear.
Power Down Operation
Settings existing immediately before the power is turned OFF (also if the power cord is
removed) are retained. This allows measurements to be performed using those saved
settings the next time the power is turned ON.
Note
The settings are stored using an internal lithium battery. The battery lasts for approximately 5
years, if it is used at an ambient temperature of 23
°
C. When the lithium battery voltage falls below
a specified level, a message is displayed on the screen (error 907) when the power switch is
turned ON. If this message appears frequently, the battery must be replaced quickly. The user
cannot replace the battery. Contact your nearest YOKOGAWA dealer to have the battery replaced.
To Make Accurate Measurements
• Allow the instrument to warm up for at least 30 minutes after turning ON the power
switch.
• After warm-up is complete, perform calibration (see section 4.6). If auto calibration is
turned ON, the calibration is automatically executed when the measurement range is
changed or when the waveform acquisition is started.
