Start Pyxis EM-400
2.1 Battery Installation
The EM-400 is powered by a 9-volt alkaline battery. Do not use rechargeable nickel
cadmium (NiCad) or lithium batteries. A typical 9V battery lasts for two months and
enables about 3000 measurements. When the battery capacity is critically low, the
EM-400 will display a LOW BATTERY warning for 5 seconds and then automatically
turn off.
Replace the battery to resume operation of the EM-400 after the battery warning. The
EM-400 will automatically turn on in the measurement mode after new battery
installation.
The EM-400 battery compartment, shown in Figure 2, is on the back side of the
instrument.
Install battery as follows:
1. Remove the battery compartment cover by loosening two screws.
2. Make sure that the smaller circular terminal (positive) of the battery is aligned with
the hexagonal socket (positive) of the battery holder and the hexagonal socket
(negative) of the battery with the circular terminal of the holder. Snap the battery
firmly into the battery holder.
3.
Replace the battery compartment cover, making sure that the sealing O-ring is
lying flat on the battery holder. To prevent the EM-400 from accidently being
turned on due to vibration, please firmly tighten the two screws.
