INTRODUCTION

INITIAL INSPECTION

SENSOR HANDLING

POWER REQUIREMENTS

This chapter provides information for the initial inspection and preparation for use of the ML2430A Series Power Meter. Shipping and storage infor mation is also included.

Inspect the shipping container for damage. If the container or cushioning material is damaged, retain until the contents of the shipment have been checked against the packing list and the instrument has been checked for mechanical and electrical operation.

If the power meter is damaged mechanically, notify your local sales repre sentative or Anritsu Customer Service Center. If either the shipping con tainer is damaged or the cushioning material shows signs of stress, notify the carrier as well as Anritsu. Retain the shipping materials for the carrier's inspection.

The sensors are enclosed in a polycarbonate case to help prevent damage. The sensor connectors, however, are exposed and are a critical part of the microwave instrument. Refer to the MA24XXA Series Power Sensor manual (10585-00004) for detailed information on proper connector care.

The ML2430A Series Power Meter can be operated from either AC line power, external DC power, or from the optional internal battery. The ML2430A Series Power Meter is intended as an Installation (Overvoltage) Category II, Insulation Category I device.

At power-on, the power meter will perform a brief power-on self test (POST). If a POST error occurs, information and available options will be displayed on the screen (See Chapter 4, page 4-3). If the POST is suc cessful, the instrument will load the last used configuration, unless Secure mode has been selected (see Chapter 4, page 4-34, or Chapter 6, page 6-68).

AC Line Power

DC Power

The ML2430A Series Power Meter can operate on AC input power of 85-264V, 50-440 Hz, 40 VA maximum. The Power Meter automatically configures itself for the voltage applied. The AC line input is protected by an internal fuse.

The ML2430A Series Power Meter can also operate from a nominal external 12-24 VDC input in the ab sence of AC line power. DC line power is protected by

ML2430A OM 2-1

POWER REQUIREMENTS INSTALLATION

a fuse mounted inside the unit, on the main board. A grounding terminal is provided on the rear panel to ground the unit during operation from a DC supply.

Battery Power

The ML2430A Series Power Meter can be operated using the optional internal battery pack. During battery operation, an icon will be displayed on measurement screens indicating the state of charge. When the remaining capacity reaches less than 10%, the icon will flash, indicating that charging will soon be required. When running from battery power, an estimate of typical-use running time remaining can be viewed using the System menu (see Chapter 4, Front Panel Operation). Note that, due to power consumption con siderations, GPIB and serial remote operation are not available when the power meter is running from the battery.

The AUTO POWER OFF feature is also available through the System menu, and can be used to automatically switch the unit to standby after a specified period of inactivity to save battery power. The timer can be set for 10 to 240 minutes, and any key press will restart the timer. This same feature will automatically switch the unit to standby when the battery is fully discharged in order to minimize the risk of overdischarge.

NOTE

The ML2430A Series Power Meter uses a high-capacity Ni-MH battery (option ML2400A-

11). Over-discharge can result in a permanent loss of battery capacity of as much as 20%. If the unit is to be stored for an extended period (longer than one week), remove the optional battery pack so as to preclude over-discharge.

For optimum battery life, store the battery pack at –20 to +50° C (–4 to +122° F) for short periods and –20 to +35° C (–4 to +95° F) for long term storage.

The ML2430A Series Power Meter will operate from AC or DC main power with this battery removed. This battery is not used for the retention of nonvolatile memory functions. Refer to Section 2-7, Battery Charging, Removal and Replacement, for further infor mation.

INSTALLATION ENVIRONMENTAL REQUIREMENTS

ENVIRONMENTAL REQUIREMENTS

Fuses

Grounding

The ML2430A Series Power Meter is designed to operate within the temperature range of 0 to 50° C (32 to 122° F) with a maximum humidity of 90% at 40° C (104° F), non-condensing. Full accuracy is specified at 5 to 35° C (23 to 95° F).

Although not recommended, operation in temperatures to –20° C (–4° F) is possible. At these temperatures, however, the liquid crystal display may exhibit excessively slow response. The soft sided carry case (part number D41310) and optional front panel cover (option ML2400A-

12) can be used to help retain internally generated heat and may improve response.

The ML2430A Series Power Meter AC and DC input lines are protected by internally mounted fuses. These fuses should only be changed by qualified service per sonnel. Replace only with fuses of the same type and rating (AC fuse is 2A, 250V, slow-blow; DC fuse is 3A, 125V, slow-blow).

The ML2430A Series Power Meter must be properly grounded. Failure to ground the instrument could be hazardous to operating personnel. The meter is sup plied with a three-conductor power cord. The instru ment is properly grounded during AC line operation when the plug is connected to a properly installed three-prong receptacle. A grounding terminal is pro vided on the rear panel to ground the unit during op eration from a DC supply.

RACK MOUNTING

ML2400A-01 Rack

Mount Installation

The ML2430A Series Power Meter can be ordered with rack mounting hardware that allows the unit to be mounted into a standard 19-inch equipment rack. There are two rack mount option kits available:

The ML2400A-01 Rack Mount option allows the installation of a sin gle ML2430A in either the left or right side rack position.

The ML2400A-03 Rack Mount option allows side-by-side mounting of two ML2430A Power Meters.

The Power Meter itself must be ordered from the factory as a rack mount-ready unit. As such, it will be fitted with rack mount top and bottom cases. These cases have extra mounting holes so that the rack mount kits can be installed. Instructions for installing the rack mount kits follow.

This section describes the assembly procedure for fitting a single ML2430A Power Meter (PM) unit into an instrument rack. The PM must be fitted with rack mount top and bottom covers before the rack mount kit can be fitted. The proce dure involves fitting the support bracket to the PM. The PM can then be loaded and secured in the rack position desired.

Figure 2-1. Model ML2430A Series Battery Compartment

The battery is shipped with a partial charge only, and should be fully charged before use.

The battery can be completely charged in about two hours with the power meter in standby mode by selecting CHARGE from the System menu (page 4-30). This selection is available only when the instrument is being powered by AC line power or external DC power greater than 21 volts. Note that the instrument will shut down during the charging cycle, and re start automatically when the charging is completed. A series of 10 beeps signals completion of the charge cycle.

The external battery charger (option ML2400A-13) can completely charge the battery in 2.5 hours.

INSTALLATION BATTERY CHARGING, REMOVAL AND REPLACEMENT

CAUTION

To avoid excessive heat build

•

up, always remove the ML2430A from the optional soft sided carrying case (D41310) before selecting fast charging.

CAUTION

• The ML2430A battery pack can leak, explode, or catch on fire if it is opened, disassembled, or exposed to fire or very high temperatures. No attempt should be made to open, repair, or modify the battery package.

For optimal battery life, the battery should be fully discharged before re charging. Repeated partial charge/discharge cycles can result in a loss of battery capacity, recoverable by applying several “conditioning” (full charge/discharge) cycles. If the power meter determines that a battery conditioning cycle is required, a message stating this requirement will be displayed on the front panel, and will remain until the battery is fully condi tioned or replaced. A number of complete conditioning cycles may be nec essary to fully condition a battery.

The ideal battery temperature ranges are:

Discharging: –20 to +50° C (–4 to +122° F)

Charging: +10 to +45° C (+50 to +113° F)

Note that charging will be inhibited if the temperature falls outside these limits.

To remove the battery, first disconnect any AC or DC input line power. Open the battery compartment as illustrated and remove the battery. Replace the battery only with an identical battery or an equivalent as recommended by an Anritsu Service Center. Ensure that the battery is correctly connected and that the battery compartment cover is securely fastened.

Note that the battery is an optional component that is not used for the retention of nonvolatile memory functions, and is not required for the Power Meter to operate from either AC or DC line sources. Serial and GPIB remote operation, however, are not available when the power meter is running from battery power.

•

When a battery pack has reached the end of its func tional life, it should be re turned to the nearest Anritsu Service Center for proper re cycling or disposal. Do not treat a used battery as normal waste.

Requirements

Preparation for

Shipment

The following paragraphs describe preparing the power meter for storage and shipment.

Preparing the power meter for storage consists of cleaning the unit and packing it with moisture-absorbing desiccant crystals. Whenever the unit is to be stored for an extended period (longer than one week), it is advisable to remove the optional battery pack. Refer to Section 2-7, “Battery Charging, Removal and Replace ment,” for instructions.

Store the unit in a temperature controlled environment that is maintained be tween –40 and +70° C (–40 to +156° F), with a maximum humidity of 90% at 40° C (104° F), noncondensing. For optimum battery life, store the battery pack at –20 to +50° C (–4 to +122° F) for short periods and –20 to +35° C (–4 to +95° F) for long term storage.

To provide maximum protection against damage in transit, the power meter should be repackaged in the original shipping container. If this container is no longer available and the power meter is being returned to Anritsu for repair, advise Anritsu Customer Service Center; they will send a new shipping container free of charge. In the event neither of these two options is possible, follow the packaging instructions below.

Use a Suitable Container

Obtain a corrugated cardboard carton with a 275-pound test strength. This carton should have inside dimensions of no less than six inches larger than the instrument dimensions to allow for cushioning.

Protect the Instrume nt

Cushion the Instrume nt

Seal the Container

Address the Con tainer

Wrap the instrument to protect the finish.

Cushion the instrument on all sides by tightly packing dunnage or urethane foam between the carton and the instrument. Provide at least three inches of dunnage on all sides.

Seal the carton using either shipping tape or an industrial stapler.

If the instrument is being returned to Anritsu for service, mark the address of the appropriate Anritsu service center (Table 2-1), the Return Materials Authorization (RMA) number, and your return ad dress on the carton in a prominent location.
