   • Factory calibration certificate, calibration equipment, certified calibration ampoules and reference devices for continuous monitoring

Installation of the transmitter

1. Laying of the supply line or transmission line
   • The cable must not be laid in the area of interference fields.
   • Do not operate the transmitter in the area of electromagnetic interference fields.
   • The permissible cross-sections for the installation must be observed.
   • The cable length must be kept as short as possible. » If an extension of the cable is required, the cross-section of the extension must not be below 0,25 mm2 .
   •  If the electronics housing and the display electronics are grounded, an appropriate equipotential bonding conductor must be provided.
2. Mounting the transmitter
   • The measuring probe must be positioned at a representative location.
   • Avoid positions of drought and unnatural temperature fluctuations.
   • Do not expose the device to direct sunlight.
   • If the sensor tube is twisted, the tightness is no longer guarantee
   • When there is a possibility of condensation, position the sensor probe slightly upwards (approx. 10 degrees angle).
   • The condensation water can then flow away from the sensor probe towards the housing or cable and drain off.
   • If it is impossible to place the unit at an upward angle, a drip nose (optional accessory) must be installed.
   • Installation inside an air duct (or at mounting locations where temperature differences between sensor probe and sensor housing may occur:
   • The sensor must be inserted fully into the opening until it stops, to avoid a temperature drop along the sensor tube. See picture:

Adjustment behavior of the sensor

• In humidity and temperature measurement, several parameters are responsible for the adjustment behavior (time until the actual measured value is displayed). The parameter responsible for the highest measuring error is a temperature discrepancy between the sensor resp. the whole measuring instrument and the material being measured resp. the air.

• Therefore, let the device adjust until the displayed temperature corresponds to the actual temperature. The graph below shows how long it takes to adjust from 20 °C to 30 °C.

•  To demonstrate the importance of temperature adjustment, the table below shows the measuring errors due to a temperature difference between the measuring instrument and the material being measured of only 1 °C, at different ambient temperatures.

| 10 °C| 20 °C| 30 °C
---|---|---|---
10 % r.h.| +/- 0.7 %| +/- 0.6 %| +/- 0.6 %
50 % r.h.| +/- 3.5 %| +/- 3.2 %| +/- 3.0 %
90 % r.h.| +/- 6.3 %| +/- 5.7 %| +/- 5.4 %

At room temperature (20 °C) and an assumed humidity value of 50 % relative humidity a temperature difference between the measuring sensor and the material being measured of 1 °C causes a measurement error of 3.2 % relative humidity.
A temperature difference of 3 °C would cause a measurement error of more than 10 % relative humidity.

Definition relative humidity

Indicates the relationship between the current water vapor pressure and the maximum possible, the so-called saturation vapor pressure. The relative humidity shows the degree the air is saturated with water vapor. Examples: 50% relative humidity: At the current temperature and pressure, the air is half saturated with water vapour. 100% relative humidity means that the air is totally saturated with water vapor. If the air has more than 100% humidity, the excessive humidity would condense or precipitate as mist.

1. Application range
   Within the normal application range (normal range) the accuracy of the device is as i ndicated. A long-term application beyond the normal application range (max. range), particularly at an air humidity of more than 80%, can lead to higher measuring errors. Back i n the normal application range, the sensor will return to the indicated accuracy automatically.

Cleaning and maintenance

Regularly cleaning and maintaining the device will ensure that it will have a long service life and stay in good condition.

1. Care instructions

   • Do not leave the device out in the rain.
   • Do not immerse the sensor in water.
   • Do not expose the device to extreme temperatures.
   • Protect the device from strong mechanical shocks and loads.

2. Cleaning the device
   ATTENTION Do not clean with fluids Water or cleaning fluid getting inside the device can destroy the device.

   • Only clean with dry materials.
   • Aluminum housing and sensor tube
   • Clean the aluminum housing and the sensor tube with a dry cloth.
   • Air humidity and temperature sensor
   • The air humidity and temperature sensor cannot be cleaned.
   • In case of a polluted sensor please contact Checkline Europe.

Checking the calibration
To do so: Calibration equipment and calibration ampoules are required.
The device, the calibration equipment and the humidity standards must have a temperature between 20.0 °C and 26.0 °C.
It is recommended to store the device, the calibration equipment and the calibration ampoules in a room with little temperature fluctuation for 24 hours.

Assembling the calibration equipment

1. Place the sealing ring over the threads of the lower part like shown in (figure 1).
2. Place the textile pad into the lower part (figure 2) and carefully pour the humidity standard onto the pad, beginning with the humidity standard of 35 % relative humidity.
3. Carefully place the upper part onto the lower part (figure 3) and tighten the upper part clockwise. » Recommendation: Keep the lower part on the table while screwing on the upper part. » If necessary, only lift the calibration equipment straight up and do not tilt or turn it over.
4. Loosen the fixing nut counterclockwise until the sensor tube of the measuring device can be inserted without excessive pressure.
5. Now carefully push the sensor tube of the measuring device into the upper part until i t stops (figure 4).
6. Secure the calibration equipment on the sensor tube by tightening the previously l oosened fixing nut.
   • Make sure to lift the device with the calibration equipment only straight up and do not tip or turn it over Otherwise you could damage the sensor.
   • Do not remove the calibration equipment from the sensor tube until specifically i ndicated otherwise.
   • Place a distance holder under the device so that the device and the calibration equipment lay horizontally on the table.

ATTENTION Damage to the sensor
By tilting or turning the device with mounted calibration equipment the sensor can be destroyed.
Only lift the device with mounted calibration equipment straight up

Determining the deviation

1. Let the sensor adjust to the humidity standard for at least 2 hours.
2. Then note down the measured relative humidity and temperature.
3. At ideal temperature conditions (device, calibration equipment and humidity standard have a temperature of 23 °C), the value printed on the humidity standard can be used as reference value.
4. In case of deviation from the factory temperature (23.0 °C), the real humidity value must first be determined according to the table below.

• Note down the real humidity value
• Compare the noted displayed measuring value with the real humidity value.
  • If the deviation revealed is below 1.5 % relative humidity, it is not recommended to recalibrate.
  • If the deviation revealed is more than 1.5 % relative humidity, please contact Checkline Europe.
• Now remove the calibration equipment from the sensor tube and repeat the procedure from “9.1 Assembling the calibration equipment”, optionally with the humidity standard 50 % relative humidity or the humidity standard 80 % relative humidity
