CHAPTER 2

Assembling your Analyzer

Input 1 or Rear Socket Channel 1 (Type 2270 only)

See item 11 in Fig.2.2 (hardware versions 1 – 3) or Fig.2.3 (hardware version 4).

This triaxial LEMO connector is used for AC or CCLD inputs to Channel 1. It can be used

when analysing electrical signals, from (for example) transducers or signal recordings. Use one

of the following cables:

• AO-0440-D-015: LEMO to BNC plug, 1.5 m

• AO-0727-D-010: LEMO to BNC jack, 1.0 m

• AO-0701-D-030: Accelerometer cable, LEMO to M3, 3.0 m

• AO-0702-D-030: Accelerometer cable, LEMO to 10–32 UNF, 3.0 m

• AO-0722-D-050: Accelerometer cable, LEMO to MIL-C-5015, 5.0 m

Input (Input Ch.2 or Rear Socket Channel 2 for Type 2270)

See item 5 in Fig.2.2 (hardware versions 1 – 3) or Fig.2.3 (hardware version 4).

This triaxial LEMO connector is used for AC or CCLD inputs to Type 2250 or to Channel 2 of

Type 2270. It can be used when analysing electrical signals, from (for example) transducers or

signal recordings. Use one of the cables listed under Input 1.

External Power

See item 6 in Fig.2.2 (hardware versions 1 – 3) or Fig.2.3 (hardware version 4).

The analyzer is powered by an internal rechargeable battery pack. An indication of available

charge is shown by the battery icon at the bottom of the screen. If the charge remaining

is low or empty, the batteries can be recharged by connecting Mains Power Supply ZG-0426 to

the ‘Ext. Power’ socket. When the power supply lead is connected, the icon will be

displayed in place of the battery icon.

CAUTION: Use specified battery charger only.

Charging below 0 °C (32 °F) is not recommended.

Note: If you charge the battery pack below 0 °C,

the lifetime of the batteries will be reduced.

Do not charge battery pack in temperatures above 60 °C.

Do not disassemble or expose battery pack to fire or water.

Battery Charge Indicator

See item 7 in Fig.2.2 (hardware versions 1 – 3) or Fig.2.3 (hardware version 4).

A battery charge light (LED) indicates when the battery pack is being charged from external

power:

• With hardware versions 1 – 3: The LED is a steady green light when external power is

applied (and the battery is charging), and a flashing green light when charging has finished

• With hardware version 4 (G4): The LED is red when external power is applied (and the

battery is charging); green when the battery is completely charged; and blue to indicate

that the unit is in stand-by and battery powered
