Great Planes Triton Jr. Charger - GPMM3152 - Manual (Page 19)

An audible BUZZER identifies when a function has started or stopped. The buzzer also alerts the user when an error has occurred. The
buzzer will also sound once for each push of a button to aid in setting up the charger. This buzzer cannot be adjusted or turned off.
When settings are adjusted in the programming, Triton Jr. will memorize these settings until changed again manually. This
single MEMORY should retain all settings even when power is removed from the charger (but all test data will be lost when
power is removed).
A backup SAFETY TIMER feature is designed to protect the charger, battery, and surrounding environment during charge. IF for some
reason Triton Jr. does not properly identify a battery having reached full charge (peak for NiCd/MH batteries) the backup safety timer
should automatically shut off charger to prevent any damage from occurring due to overcharge. The safety timer settings are 1.5 hours
(90 minutes) for NiCd and NiMH batteries, and 2 hours (120 minutes) for LiPo and Li-Ion batteries.
At the beginning of charge the voltage for NiCd and NiMH batteries can be somewhat unstable. This instability could possibly cause
the peak detection circuitry to accidentally trip and stop charge, which would cause the battery to NOT become properly charged. To
avoid this, Triton Jr. uses a PEAK DELAY AT START function whereby the peak detection circuit is automatically turned of during the
first 3 minutes of charge. After 3 minutes, the peak detection circuitry will automatically turn on and allow Triton Jr. to properly, accurately
detect peak when it actually occurs.The “peak detection” circuit automatically stops delivering charge to NiCd and NiMH batteries when
Triton Jr. actually sees that the battery’s voltage actually drops very slightly just after full charge has been reached.The charger’s ability
to identify this very tiny voltage is called PEAK SENSITIVITY. Triton Jr. is set to have a 8mV per cell peak sensitivity for NiCd batteries,
and 5mV per cell for NiMH batteries. These sensitivity settings are not adjustable.
