3.2 Getting Started
3.2.1 Connecting to Power Source
Using AC Power Source
To use the AC power source, connect one end of the power cord with the AC power input on the equipment’s back
panel and the other end with a wall AC mains outlet.
WARNING
Always use the accompanying power cord with the monitor.
Use the battery if the integrity of the protective earth conductor or the protective earthing system in the
installation is in doubt.
Using a Battery
This monitor can be equipped with rechargeable lithium-ion battery. If a battery is installed, the monitor system
automatically switches to the battery for power if AC power is interrupted.
NOTE
When a battery has been stored for a long time, or the battery is depleted, recharge the battery at once.
Otherwise, the low battery may not be sufficient to power the monitor if the AC power is unavailable.
Refer to Chapter 24 Batteries for detail.
Connecting Accessories
Insert the connector of accessory cables necessary for the measurements to be performed by your monitor to the
corresponding connector on the monitor. For details about the parameter connectors, refer to 2.3.2 Side View
3.2.2 Turning Power On
Once the monitor is installed, before beginning measurements:
1. Check the monitor and plug-in modules for any mechanical damage, and make sure that all external cables,
plug-ins and accessories are properly connected.
2. Check the power supply specification is met if mains power is used. Only use a power outlet that is properly
grounded.
3. Plug the power cord into the AC power source. If you run the monitor on battery power, ensure that the battery
is sufficiently charged.
4. Press the power on/off switch on the monitor’s front panel.
The monitor will perform alarm system self-test during start-up. After pressing the power on/off button, the system
shows a “Loading…” screen, sounds a beep and the alarm lamp simultaneously turns yellow, then red, and then turns
off, followed by the start-up screen being shown. Then the start-up screen disappears. The alarm system self-test
succeeds. The monitor enters the normal monitoring screen.
