PIM Master™ Passive Intermodulation Analyzer with Site Master™ Cable & Antenna Analyzer (331) and 2-Port Options (703) User Guide : Instrument Care : Battery Care
 
Battery Care
The PIM Master is supplied with a rechargeable battery that could potentially leak hazardous compounds into the environment. These hazardous compounds present a risk of injury or loss due to exposure. Anritsu Company recommends removing the battery for long-term storage of the instrument and storing the battery in a leak-proof, plastic container.
Environmental storage requirements: 
Storage Temperature Limits: –20 °C to +50 °C, Relative Humidity ≤ 80 %
The battery packs should be stored in an environment with low humidity, free from corrosive gas, at a recommended temperature range <20 °C. Extended exposure to temperatures above +40 °C could degrade battery performance and life.
Battery charging limits: 0 °C to +45 °C, Relative Humidity ≤ 80 %
The battery supplied with the PIM Master may need charging before use. Before using the instrument, the internal battery may be charged either in the instrument, using either the AC Adapter or the 12-Volt DC adapter, or separately in the optional Dual Battery Charger. Anritsu part numbers for these accessories are in your Technical Data Sheet/Product Brochure.
Use only Anritsu approved battery packs. Anritsu part numbers are in the Technical Data Sheet.
Recharge the battery only in the PIM Master or in an Anritsu approved charger.
When the PIM Master or the charger is not in use, disconnect it from the power source.
Do not charge batteries for longer than 24 hours. Overcharging may shorten battery life.
If left unused, a fully charged battery will discharge itself over time.
To prevent instrument damage, Anritsu Company recommends removing the battery for long‑term storage of the instrument.
Temperature extremes affect the ability of the battery to charge: allow the battery to cool down or warm up as necessary before use or charging.
The battery can be charged and discharged hundreds of times, but it will eventually wear out.
The battery may need to be replaced when the operating time between chargings becomes noticeably shorter than normal.
Never use a damaged or worn out charger or battery.
Storing the battery in extreme hot or cold places will reduce the capacity and lifetime of the battery.
 
Battery Replacement
The battery compartment access is on the bottom of the PIM Master.
Battery Compartment - Open
 
The battery snaps into the compartment door assembly. Orientation of the battery is important. A diagram inside the battery door assembly and another diagram inside the PIM Master compartment show an image of the battery. Notice that the connector end of the battery is oriented away from the latch mechanism, and the battery connection openings are up, or away from the plate of the door assembly.
The image in the battery door assembly shows the orientation in which you should see the battery as you place the battery into the door assembly (see Figure: Battery and Cover Plate). Inside the PIM Master compartment is a reflected image of the battery (see Figure: Battery Orientation Diagram Inside Battery Compartment) to show how the battery connectors align with the pins inside the compartment. As you place the battery door assembly into the battery compartment, the battery connectors and the reflected image should match, as if you were seeing the connectors reflected in a mirror.
To avoid connector pin damage, you must not press the battery downward onto the connector pins within the battery compartment. You must position the battery door assembly so that the battery connections can slide lengthwise onto the connector pins as you seat the door assembly against the bottom of the PIM Master. The tab on the door fits into a slot located on the edge of the case adjacent to the connector pins.

Inserting the Battery into the Case
Closing the Battery Cover Plate
Place the blank edge of the door assembly into the PIM Master first and ensure that the connector end of the battery is as deep into the case as possible. This is to orient the battery connector openings with the connection pins inside the pm.
Slide the door assembly lengthwise into the PIM Master case making sure that the tab on the door assembly engages with the slot in the case. Continue moving the door assembly to seat the battery connections. When the latch is aligned, close the door and twist the latch to lock the door in place. Turn the latch handle flat so that the PIM Master can sit flat when upright.
