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. Connecting a

weather station or a GPS receiver can decrease

battery operating with up to 20%

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 hr

period

Storage

INTERNAL FLASH-RAM (NON-VOLATILE)

For user setups and measurement data:

• Hardware versions 1 – 3: 20 MB

• Hardware version 4:512 MB

EXTERNAL SECURE DIGITAL MEMORY CARD

SD and SDHC Card: For store/recall of measurement

data

EXTERNAL COMPACT FLASH MEMORY CARD

(Hardware Versions 1 – 3 Only)

CF Card: For store/recall of measurement data

USB MEMORY STICK (Hardware version 4 only)

For store/recall of measurement data

Environmental

WARM-UP TIME

From Power Off: <2min

From Standby: < 10 s for prepolarized microphones
