CHAPTER 3 HOW TO USE THE HANDHELD CONTROLLER
Safety Precaution
The device contains Li-ion rechargeable batteries that are potentially
hazardous, and may pose a fire-risk when mishandled or subject to
temperatures beyond the specified maximum.
Never attempt to operate, recharge, or subject the device to temperature
beyond 60°C or below -20°C (-4°F - 140°F).
Never submerge the controller in liquid.
Always power-down the device, disconnect charger or any external power
source and unplug sensor connector before performing any servicing to the
Flow Pulse Handheld or the Flow Pulse.
Charging the Controller
A charger is supplied for charging the battery on the handheld. Other
chargers may be used, but the power rating must be within 12-18 VDC and
fused @ 2A max.
The battery indicator icon
provides indication of the available
charge on the Flow Pulse Handheld.
During charging, the battery icon will have a blue background
to
indicate that the charger is present.
During charging, the charge LED lights up with red when the battery
contains approximately 90% charge or less, and turns green when the
battery has more than 90% charge. When the battery level falls to 0%, the
Flow Pulse Handheld will be automatically powered down. This is to avoid
over-discharging the battery, which may damage the batteries.
Important Information
Charging should only be performed within an ambient temperature range of 0 to
45°C (32 to 113°F). Never perform charging where contact with liquid is
possible.
Always disconnect the charger and the Flow Pulse sensor before attempting any
form of cable or wire servicing.
