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 VAC; 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)
• Dual-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
40
C charging time will be prolonged. With External Charger ZG-0444
(optional accessory), typically 5 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
CLOCK
Back-up battery powered clock. Drift < 0.45 s per 24 hour period
Storage
INTERNAL FLASH-RAM (NON-VOLATILE)
For user setups and measurement data: 512 MB
EXTERNAL SECURE DIGITAL MEMORY CARD
SD and SDHC Card: For store/recall of measurement data
USB MEMORY STICK
For store/recall of measurement data
Environmental
WARM-UP TIME
From Power Off: < 2 minutes
From Standby: < 10 seconds for prepolarized microphones
TEMPERATURE
IEC 60068–2–1 & IEC 60068–2–2: Environmental Testing. Cold and
Dry Heat.
Operating Temperature: –10 to + 50
C (14 to 122F), < 0.1 dB
Storage Temperature: –25 to +70
C (–13 to +158F)
HUMIDITY
IEC 60068–2–78: Damp Heat: 90% RH (non-condensing at 40
C
(104 F)).
Effect of Humidity: < 0.1 dB for 0% < RH < 90% (at 40°C (104°F) and
1 kHz)
