–
operation time depends on the measurement period, the presence of an SD/MMC card, and the ambient temperature:
- 5 years (recording period > 10 min., recording in internal memory, data copied only through the USB, 20 - 30 °C)
- 8 months (measurement period 10 s, internal memory, data copied only through the USB, 20-30 °C)
- 1.5 years (measurement period > 10 min., recording on an SD/MMC card, 20-30 °C)
5 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
5. HOUSING DIMENSIONS, DESCRIPTION OF CONNECTIONS AND EXTERNAL ELEMENTS
In the case of wall-mounted installation, in order to make mounting holes, the back wall of the housing can be
uninstalled (chapter 14) and used as a template.
