Once in Diagnostic Mode, Version 2.00 and above will allow switching between diagnostic and standard modes by pressing and holding both the [Y] and [MODE] keys. V. Diagnostic and Service Test Procedures: 1.0 Power supply / Battery / Charger 1.1 Battery Voltage Test: 1.1.1 Turn off the power to the MultiRAE. Open the instrument cover by removing the 2 flat head screws from the backside (see Figure 1). Figure 1 8
1.1.2 Carefully remove the battery pack or alkaline battery adapter from the unit. Make sure that the battery or adapter is plugged into the jack. 1.1.3 Unplug the battery from the battery jack connected to the PC board of the MultiRAE. Visually inspect the wires between the battery pack or adapter and the connector, and between the jack and the PC board, for signs of broken or frayed wires or loose connector pins. 1.1.4 Use a voltmeter to measure the voltage between the 2 outside pins of the connector on the battery pack. Be careful to avoid shorting the two pins as this could blow the internal fuse and/or damage the batteries. If the voltage is less than 4.2V the unit will not turn on. If using alkaline (AAA) cells, replace them with fresh cells when the voltage is less than 4.4V. When the voltage is below 4.4V, charge the batteries, either in the unit or on the external charger (RAE part number 008-3027). After replacing or recharging the batteries, check the voltage again. Fresh alkaline batteries should read over 6V. Fully charged Li-Ion or Ni-Cad batteries should read over 4.8V. 1.1.5 If the voltage reads 0, then the internal fuse is blown or there is a broken wire. Replace the battery pack or adapter. 1.3 Battery loading 1.3.1 Remove the battery from the unit. Set the DC power supply to 4.8V DC. Connect the negative output to pin 1 (black wire) of the spare battery connector. Connect the positive power supply output to the positive side of a current meter. Connect the negative side of the current meter to pin 3 (red wire) of the battery connector (see figure 2). DC POWER SUPPLY + - + - DC CURRENT METER 3 1 Figure 2 1.3.2 Plug the connector into the mating connector in the MultiRAE. Current should be about 3 ma with the unit off. Turn on the unit and wait for it to complete the start up tests. The current will depend on the configuration of the MultiRAE: Basic unit: 20 mA 9
