Operating Temperatures - ELPRO ECOLOG TN2 Handbuch

2. Applications and Safety Regulations

2.1 Operating Temperatures

- The loggers can be used in the temperature range between -35° and +55°C. However, it becomes
increasingly difficult to read the display when the temperature falls below -20°C.
- Lithium battery passivation, due to long-term use at temperatures above 40°C, can result in temporary read
problems (self-discharge protection). This can be rectified by repeated evaluation.
- Long-term use at low temperatures down to -40°C does not present any problems, but may reduce the
quality of the display.
- We can not guarantee that the logger will always function properly if it is implemented at temperatures below
-40°C. Experience has shown that the battery freezes at approx. -50°C, that it is no longer possible to
perform measurements and that the timer tracking function can be temporarily interrupted. To make further
operation possible, the logger must be reprogrammed when room temperature is reestablished.
- Temperatures exceeding 55°C can result in permanent discoloration of the display.
- Temperatures exceeding 70°C can result in deformation of the housing.
2.2 Exceptional Environmental Conditions
Pay attention to the following when loggers are used under exceptional environmental conditions:
- UV rays diminish the stability of the housing
- IR radiation (warmth) and superheated steam can result in deformation of the housing
- A vent hole into the battery cover (
- There is a risk that the battery may explode if the logger is used in conjunction with microwaves
2.3 Precautionary Measures for Handling Units with Lithium Batteries
- Do not short-circuit batteries or throw into fire: Danger of explosions
- Do not subject the batteries to mechanical stress and do not dismantle them. The leaking battery fluid is
highly corrosive and lithium can generate severe heat when it comes into contact with moisture or it can
ignite fire.
- Do not heat up battery-driven units to temperatures exceeding 100°C: Danger of explosions
- Avoid violent knocks and blows
- Follow the manufacturer's specifications for battery storage
2.4 Serviceable Life
Recommended max.
TNx 18 month
21 month
THx 10 month
13 month
TPx 10 month
15 month
At temperatures above 45°C the self-discharge of the battery increases, serviceable life will be reduced by
approximately 1/3

This indicator (see page 13) is going to be switched on at the time the battery life ends.
Please change the battery according to the procedure described in chapter
2.8 at your next possibility.
