A complete open, short, and load calibration must be performed before calibration can be turned on. Valid distance to fault plots require a non-zero frequency span. Distance-to-fault measurements cannot be performed with CAL OFF. Attempting to print a display with no printer selected. Select a printer, then retry. Attempting to perform a Power Monitor zero adjust function with no RF detector connected to the Site Master. Attempting to perform a Power Monitor zero adjust function with an input of greater than –20 dBm. Attempting to enter Power Monitor mode with no Option 5 installed. 2-17 Chapter 2 Functions and Operations Battery Information Charging a New Battery The NiMH battery supplied with the Site Master has already completed three charge and discharge cycles at the factory and full battery performance should be realized after your first charge. NOTE: The battery will not charge if the battery temperature is above 45. Cor below 0. C. Charging the Battery in the Site Master The battery can be charged while installed in the Site Master. Step 1. Turn the Site Master off. Step 2. Connect the AC-DC adapter (Anritsu part number: 40-115) to the Site Master charging port. Step 3. Connect the AC adapter to a 120 VAC or 240 VAC power source as appropriate for your application. The green external power indicator on the Site Master will illuminate, indicating the presence of external DC power and the battery will begin charging. The indicator will remain lit as long as the battery is charging. Once the battery is fully charged, the battery indicator will turn off. If the battery fails to charge, contact your nearest Anritsu service center. Charging the Battery in the Optional Charger Up to two batteries can be charged simultaneously in the optional battery charger. Step 1. Remove the NiMH battery from your Site Master and place it in the optional charger (Anritsu part number 2000-1029). Step 2. Connect the lead from the AC-DC adapter to the charger. Step 3. Connect the AC-DC adapter to a 120 VAC or 240 VAC power source as appro priate for your application. Each battery holder in the optional charger has an LED charging status indicator. The LED color changes as the battery is charged: Red indicates the battery is charging Green indicates the battery is fully charged Yellow indicates the battery is in a waiting state (see below). A yellow light may occur because the battery became too warm during the charge cycle. The charger will allow the battery to cool off before continuing the charge. A yellow light may also indicate that the charger is alternating charge to each of the two batteries. A blinking red light indicates less than 13 VDC is being supplied to the charger stand. Check that the correct AC charger adapter is connected to the charger stand. If the battery fails to charge, contact your nearest Anritsu Service Center. 2-18 Chapter 2 Functions and Operations The NiMH battery will last longer and perform better if allowed to completely discharge before recharging. For maximum battery life, it is recommended that the NiMH battery be completely discharged and recharged once every three months. Battery Charge Indicator When the AC-DC adapter is unplugged from the Site Master, the battery indicator symbol will be continuously displayed at the top left corner of the Site Master display (Figure ). BATTERY INDICATOR Figure . Site Master Battery Indicator A totally black bar indicates a fully charged battery. When LOW BATT replaces the battery indicator bar at the top left corner, a couple of minutes of measurement time remains. If a flashing LOW BATT is accompanied by an audio beep at the end of each trace, the battery has approximately one minute of useable time remaining. Once all the power has drained from the battery, the Site Master display will fade. At this point, your Site Master will switch itself off and the battery will need to be recharged. Battery Life It is normal for NiMH batteries to self-discharge during storage, and to degrade to 80% of original capacity after 12 months of continuous use. Figure . NiMH Battery Storage Characteristics 2-19 Chapter 2 Functions and Operations The battery can be charged and discharged 300 to 500 times, but it will eventually wear out. The battery may need to be replaced when the operating time between charging is noticeably shorter than normal. Important Battery Information . With a new NiMH battery, full performance is achieved after three to five complete charge and discharge cycles. The NiMH battery supplied with the Site Master has already completed three charge and discharge cycles at the factory. . Recharge the battery only in the Site Master or in an Anritsu approved charger. . When the Site 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. Storing the battery in extreme hot...
