MIN/MAX Function The MIN / MAX function can be used to record the lowest and highest values measured for each measurand since the last reset or the last interruption of the power supply. Highest measured value: MAX 1. Select the required measurand (UP / DOWN button) 2. To display the maximum value, press the UP button and hold it down for approx. 5 s.

Page 16: Velocity And Temperature Calibration
Fig. 11 Incorrect installation 1-point or 2-point Calibration The EE75 sensor can be calibrated in 2 different ways 1-point v/T calibration Quick and easy option for obtaining accurate measuring results at a specific working point. 1-point calibration should only be used for very limited working ranges. -
Page 17: General Information On 2-Point V/T Calibration
▪ The high calibration point should be in the upper third of the measuring range. Calibration / adjustment must be performed using the V/T-CAL HIGH function. Example EE75 T3***HV23 - measuring range = 0 ... 2 m/s (0...400 ft/min). Low calibration point (V-CAL LOW) should be around 0.4 m/s (0...0.7). High calibration point (V-CAL HIGH) should be around 1.8 m/s (1.4...2). -
Page 18: Calibration Procedure Using Buttons On The Display Module (Optional)
User Manual EE75 6.3.1 Calibration Procedure Using Buttons on the Display Module (Optional) 1. Insert the sensor head in the temperature reference system. 2. Allow it to stabilise (min. 15 minutes). The greater the difference in temperature between the measuring probe and the reference system, the longer the required stabilisation time. -

Page 25: Response Time
(jumper position). 10.4.5 Cross Section The EE75 allows volumetric flow to be displayed in [m³/min] or [ft³/min.] (refer to chapter 5.4 Display Module with Buttons (Optional) - Measurands). The volume is calculated based on the flow velocity measured and the cross section. Consequently, the cross sectional area of the duct must be entered in [m²] or [ft²]. -
Page 26: Probe Cable
This virtually rules out additional measuring errors due to the modified cable length. Example You order an EE75 T3***K5 (5m / 16.4ft cable length) and then cut the cable with 3m (9.8ft). The new cable length of 2m (6.6ft) should be entered and uploaded using the “Write” function. -

Clicking on the “Velocity calibration” button opens the menu window shown below. 5. Enter the velocity displayed by the reference system in the “Reference value” input field. 6. Clicking “Save” adjusts the EE75 measuring value with the reference value. 7. In the case of 1-point calibration, the process is now complete.
