SmartReader Plus Data Logger

1.14.2 Setup

Make sure to enable each channel you want to use. If you are not using a channel, disable it

in order to save memory.

Internal Temperature

Internal Relative Humidity

External 5VDC

NOTE: When you activate the RH channel, you must also enable its

corresponding temperature channel, as well, in order to temperature compensate

the RH sensors.

Precautions

The Conservation Logger's RH Sensor is designed for long-term trouble-free performance, but

there are a few precautions to keep in mind to maximize the benefit it can give you.

· Never expose the sensor to organic solvents or ionic-laden liquids. Any chemical

compound that attracts polymers may affect the sensor.

· The RH sensor is particularly susceptible to contamination by sulfur gases and sulfur

compounds. DO NOT SMOKE NEAR THE LOGGER!

· Always return your Conservation Logger to a re-sealable plastic bag during non-use to

maximize the in-calibration life of the RH sensor.

1.14.3 Accessories

You can obtain replacement RH Sensors, remote temperature probes, temperature and

relative humidity probes for use with your Conservation Logger.

The Conservation Logger can also be combined with the Telaire 7001 Handheld Monitor.

1.14.4 Relative Humidity Calibration

Each relative humidity sensor has been individually calibrated in an environmental chamber

with standards traceable to the National Institutes of Standards and Technology (NIST).

The Conservation Logger is supplied with a calibration certificate which provides calibration

values. These calibration values must be entered and stored in the logger during initial setup.

If your RH sensor is out of calibration, you can simply replace it with a new one.

NOTE: A straight replacement of the RH sensor will introduce an additional +2%

tolerance on the RH accuracy. Calibration of the RH channel with the new RH

sensor is recommended.

In the event that you wish to confirm the RH calibration of your sensor, you can perform your

own field test. Refer to Appendix B Temperature and Relative Humidity Calibrations for more

information on RH testing.
