For Making Accurate Measurements
• Turn ON the power switch and allow the instrument to warm up for at least 30
minutes.
• Perform zero-level compensation after warm-up (see section 4.4, “Performing Zero-
Level Compensation”).
Shut Down Operation
The setup parameters that exist immediately before the power switch is turned OFF are
stored in memory. The same is true when the power cord gets disconnected from the
outlet. The next time the power switch is turned ON, the instrument powers up using the
stored setup parameters.
Note
A lithium battery is used to retain the setup parameters. When the lithium battery voltage falls
below a certain level, a message is displayed on the screen (see section 16.2) when the
power switch is turned ON. When this message appears frequently, the battery must be
replaced quickly. The user cannot replace the battery. For battery replacement, contact your
dealer. For information regarding battery life, see section 16.6.
