Power
EXTERNAL DC POWER SUPPLY REQUIREMENTS
Used to charge the battery pack in the instrument
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 to 120/200 to 240 VAC; 47 to
63 Hz
Connector: 2-pin IEC 320
BATTERY PACK
Rechargeable Li-Ion battery
Part No.: QB-0061
Voltage: 3.7 V
Capacity: 5200 mAh nominal
Typical Operating Time: >10 h (screen backlight
dimmed); >7 h (full screen backlight)
Battery Cycle Life: >500 complete charge/discharge
cycles
Battery Indicator: Remaining battery capacity and
expected working time may be read out in % and 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 instrument, 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 40°C
charging time will be prolonged. With External Charger
ZG-0444 (optional accessory), typically five hours
Note: It is not recommended to charge the battery at
temperatures below 0°C (32°F) or over 50°C (122°F).
Doing this will reduce battery lifetime
