−
operation time depends on the measurement period, the presence of an SD/MMC card, the operation mode of the LCD display, and the ambient
temperature:
−
5 years (recording period > 10 min., recording in internal memory, data copied only through the USB, LCD in the economy mode, 20-30 °C)
−
20 months (measurement period > 10 min., recording in internal memory, data copied only through the USB, LCD in the continuous mode,
20-30 °C)
−
7 months (measurement period 10 s, internal memory, data copied only through the USB, 20-30 °C)
−
1.5 year (measurement period > 10 min., recording on an SD/MMC card, LCD in the economy mode, 20-30 °C)
−
4 months (measurement period 10 s, recording on an SD/MMC card, 20-30 °C)
−
an unused SD/MMC card installed in the socket also reduces the operating time of a battery
−
it takes about 2 min. to transfer the entire content of the internal memory (4 MB) onto an SD/MMC card and it consumes about 1-2 mAh of the
battery’s capacity (tested on SanDisk and Kingston memory cards)
−
by using an accessory power supply device, the operating time of a new battery can be extended to about 8 years
