Operating Precautions
9
• The battery pack is subject to self-discharge. Be sure to charge the bat-
tery pack before initial use.
• The battery pack is a consumable. If the battery capacity remains very
low after correct recharging, the useful battery life is at an end.
• Battery pack lifetime (to at least 60% initial full-charge capacity) is about
300 charge/discharge cycles.
• To prevent battery pack deterioration when the battery will not be used
for 1 month or longer, remove it and store it in a dry location with an
ambient temperature range of between -20 to 30°C. Be sure to discharge
and charge it every two months. Long-term storage at low battery capac-
ity will reduce performance.
• During battery operation, the HiLogger automatically turns off when bat-
tery charge is depleted. Leaving the HiLogger in this state for a long time
may cause over-discharge, so be sure to turn the HiLogger's power
switch off.
• When the HiLogger has turned off automatically due to low battery
charge, turn the power switch off and connect the AC adapter (or install
new batteries), then allow about 30 seconds before switching back on. If
the HiLogger is turned on too soon, it may turn off again automatically.
Using the AC Adapter
• Use only the supplied Model 9418-15 AC Adapter. AC adapter input
voltage range is 100 to 240 VAC (with ±10% stability) at 50/60 Hz. To
avoid electrical hazards and damage to the HiLogger, do not apply
voltage outside of this range.
• Turn the HiLogger off before connecting the AC adapter to the
HiLogger and to AC power.
• To avoid electrical accidents and to maintain the safety specifica-
tions of this HiLogger, connect the supplied power cord only to a 3-
contact (two-con ground) outlet.
