1. Only for model T2 (duct mounting). Drill the hole for inserting the probe into the duct wall,Fig. 7 on
page 11. The relevant position of top left mounting screw of the back cover with respect to the probe
center:
2. FixthebackcoverofEE23ontothewall/panelusing4screws(diametermax.4.2mm(0.2”);not
included in the scope of supply).
The device shall be mounted with the cable glands pointing downwards or horizontal.
3. Wiretheterminalsinsidethebackcoveraccordingto„Fig.10Connectiondiagram“onPage12.
4. Insert the middle (active) part into the back cover. By this the connection pins of the middle part will
plug into the terminals of the back cover and thus realize the electrical connection.
5. Place the front cover onto the middle part and close tight the enclosure using the four screws included
in the scope of supply.

Mounting onto DIN rails
EE23 with polycarbonate enclosure can be mounted also on DIN rails with the bracket HA010203 (not
includedinthescopeofsupply,see“spareparts/accessories”).
4.2 Mounting the Sensing Probe
Whenever possible place the entire probe inside the space to be monitored.
In case of mounting the probe into a partition wall, it is of paramount importance for accurate mea-
surement to avoid T gradients along the probe. In case of large T difference between the two sides of
the wall, it is highly recommended to insert the probe completely (up to the cable outlet) into the wall.
Should this not be possible, place a thermal isolation layer on the part of the probe outside the wall (on
the cable side).
ForprobemountingintoapartitionwallusethemountingangesHA010201forprobediameter12mm
andHA010208forprobediameter5mm.NeitherthemountingangesnortheEE23probesarepres-
sure rated and as such they are not appropriate for pressure tight mounting. For pressure tight require-
ments please see www.epluse.com for appropriate products such as EE310.

Operating manual EE23 humidity / temperature sensor
For applications where condensation is likely to happen, certain ways of mounting are required.
• For probe hanging onto its cable from the ceiling, use the drip water protection HA010503 (not inclu-
dedinthescopeofsupply,see“spareparts/accessories”).Thisprotectstheprobeandthesensing
head against water dripping along the cable.
• For horizontal mounted probe, a drip water point should be made just before the probe.

5 Calibration / Adjustment
5.1 Denitions
Calibration
The calibration documents the accuracy of a measurement device. The device under test
(specimen)iscomparedwiththereferenceandthedeviationsaredocumentedinacalibrationcerti-
cate. During the calibration, the specimen is not changed or improved in any way.
Adjustment
The adjustment improves the measurement accuracy of a device. The specimen is compared with the
reference and brought in line with it. An adjustment can be followed by a calibration which documents
the accuracy of the adjusted specimen.
For general calibration / adjustment guidelines and for the choice of humidity reference devices please
see“CalibrationInstructions”at www.epluse.com/ee23
The 2-point adjustment is recommended for best accuracy over a wide RH and / or T range.
Always start the 2-point adjustment with the lower adjustment point RH_low / T_low, followed by the
higher adjustment point RH_high / T_high.
The span between the two adjustment points must be:
 |RH_high–RH_low| >30%RH
 |T_high–T_low| >30°C(54°F)
The 1-point adjustment should be used only when the RH and/or T range of interest is rather narrow.
The RH resp. T adjustment point should be ideally in the middle of the range of interest.
Example:
In a climate controlled environment with 40% < RH < 60% and 15 °C < T < 25 °C (59 °F < T < 77 °F),
1-point adjustment shall be performed at 50 % RH and 20 °C (68 °F).
1-point adjustment leads to very good accuracy within the range of main interest at the cost of the
accuracy beyond this range.
5.2 Adjustment of EE23 Model T1, T2, T4 and T6
