Power
EXTERNAL DC POWER SUPPLY REQUIREMENTS
Used to charge the battery pack in the analyzer
Voltage: 8 – 24 V DC, ripple voltage < 20 mV
Current Requirement: Min. 1.5 A
Power Consumption: < 2.5 W, without battery charging, < 10 W when
charging
Cable Connector: LEMO Type FFA.00, positive at centre pin
EXTERNAL AC MAIN SUPPLY ADAPTOR
Part No.: ZG-0426
Supply Voltage: 100 – 120/200 – 240 V AC; 47 – 63 Hz
Connector: 2-pin IEC 320
BATTERY PACK
Part No.: QB-0061 Rechargeable Li-Ion battery
Voltage: 3.7 V
Capacity: 5200 mAh nominal
Typical Operating Time:
• Single-channel: >11 h (screen backlight dimmed); >8.5 h (full screen
backlight)
• 2-channel: >7.5 h (full screen backlight)
Use of external interfaces (LAN, USB, WLAN) will decrease battery
operating time
Battery Cycle Life: > 500 complete charge/discharge cycles
Battery Aging: Approximately 20% loss in capacity per year
Battery Indicator: Remaining battery capacity and expected working
time may be read out in % and in time
Battery Fuel Gauge: The battery is equipped with a built-in fuel gauge,
which continuously measures and stores the actual battery capacity in
the battery unit
Charge Time: In analyzer, typically 10 hours from empty at ambient
temperatures below 30°C. To protect the battery, charging will be
terminated completely at ambient temperatures above 40°C. At 30 to
