External diameter of supply cable: 10-12mm (0.39-0.47")
Maximum wire cross section for connecting cable: 1.5mm² (AWG 16)
The protection of the supply cable against excess current and short-circuit must be
designated to a wire cross section of 0.8mm² (AWG 18) (6A fuse).
National regulations for installation must be observed!
Bottom and middle part of the metal housing must be grounded during operation!
The procedure of dew point and frost point calibrations are equal with
the procedure of humidity calibrations!
The EE23 transmitter series can be calibrated in two ways:
-
1-point humidity / temperature calibration: quick and simple calibration on a defined
humidity / temperature point (working point).
-
2-point humidity / temperature calibration: simple calibration for accurate measuring results over
the whole humidity / temperature working range.
•
To reach a temperature balance it is recommended to keep the transmitter and the
reference chamber (e.g. HUMOR 20,...) for minimum 4 hours in the same room.
•
D uring calibration procedure it is important to keep the temperature constant!
•
For calibration the humidity sensor probe must be stabilised at least 30 minutes in
the reference chamber.
•
Replace a used dirty filter cap before calibration!
2-point humidity calibration / 2-point temperature calibration
For accurate adjustment over the whole working range a two point calibration is recommended.
•
S tart calibration at the low calibration point!
•
T he difference between the two calibration points should be > 30%RH / > 30 degC
2-point humidity calibration procedure / temperature calibration procedure (Start at low
calibration point):
1. At the beginning of a humidity calibration set the jumper to CAL RH
temperature calibration set the jumper to CAL T.
2. Insert the sensor probe into the reference humidity / reference temperature 1
(low calibration point) and stabilise for at least 30 minutes.
3. BUTTON S2: Pressing the button for 3 seconds starts the procedure for the low
calibration point. The calibration mode is indicated by the lit LED "D1" and by the
symbol "CAL<" on the LC display.
