Safety instructions

Caution! Risk of injury at the temperature sensor! Devices with insertion probes entail the risk of stab injuries due to the pointed probe design.

• Handle insertion probes with care!
• Fit a protective cap on the measuring probe if the probe is not in use!
• Do not put the device down with the sensor tube pointing upwards. Empty batteries and batteries of inferior quality can leak more easily, which can destroy the device.
• Please also observe the instructions in the chapter “Operation and Maintenance”.

Caution!
There is an immediate danger to life if live parts come into contact with the temperature sensor!

• Therefore, do not conduct measurements on or in the direct vicinity of live parts or lines.
• Never plug the temperature sensor into sockets, etc.

Note

• This device does not belong in children’s hands!
• The device and sensor are not designed for continuous contact with foods.

Intended use
The device is a water-protected thermometer for precise temperature measurements . The special design of the ECO 122 makes it a convenient insertion thermometer for:

• soft soils
• compost
• agricultural windrows
• bulk material

Qualified personnel
For commissioning, operation, and maintenance, the relevant personnel must have adequate knowledge of the measuring process and the significance of the measurements. The instruc-tions in this document must be understood, observed, and followed. To avoid any risks arising from the interpretation of the measurements in the concrete application, the user must have additional expertise. The user is solely liable for damages/danger resulting from misinterpretation due to inadequate expertise.

Operation

Opening the configuration menu

1. Press the Function key for 2 seconds to open the Configuration menu.
2. (ONF appears in the display. Release the Function key.

time in seconds, during which no buttons have been pressed
 | ON| No automatic shut-off of the backlight
UN, T| Display unit
 | °(| Temperature display in °C
 | °F| Temperature display in °F
IN, T| Factory settings
 | NO| Use current configuration
 | YES| Reset the device to factory settings.

After confirming with the function button, the display shows: IN, T DONE

Adjustment of the measuring input
The temperature input can be adjusted with the zero point correction and the gradient correction. If an adjustment is made, you change the pre-adjusted factory settings. This is signaled with the display text T.OF or T.SL when switching on.

1. Switch the device off.
2. Hold the down button and press the On/Off button briefly to switch on the device and open the Adjustment menu.
3. The display shows the first parameter. Release the down button.

The formula used by the device

• Temperature = °C: Display = (measured value – T.OF) (1 + T.SL / 100) Temperature = °F: Display = (meas. value – 32 °F – T.OF) (1 + T.SL / 100) + 32 °F
• Adjustment example: Temperature unit= °C, the adjustment is carried out in 2 separate steps at 0 °C (e.g. ice water) and at a reference temperature (e.g. clinical thermometer with water bath 37 °C).
  • First, set the values of t.oF and t.SL in the adjustment menu to 0

Zero point

• Set the temperature probe to 0 °C and let it adjust.
• Start the adjustment menu and enter the display value at 0 °C for t.oF
• After leaving the menu, the device should now display 0.0 °C.

Slope

• Set the temperature sensor to the reference temperature and let it adjust.
• Calculate slope correction:
• Start the adjustment menu and enter the calculated value at t.SL
• Exit the menu, the device should now display the reference temperature.

Measurement Basics

Sensor/device accuracy
Penetration into the medium to be measured should be done without exerting much force. Try to exert the force on the axis of the probe tube to avoid creating a lever effect on the housing. Never use tools (e.g. a hammer) to knock the sensor tube into the ground via the device housing! If you encounter strong resistance when piercing (high compaction, stones), please try to pierce at another suitable place in order not to damage the tip or the device. If this is not possible, you can pierce an appropriate hole with another rod (e.g. reinforcing iron).

Possible measuring errors

Immersion depth

• Liquid, soil:
  • to a depth of at least 100 mm (and then stir). Otherwise, measuring errors can occur due to the heat transmission of the sensor tube if the immersion depth is too shallow.

Surface effects and poor heat transfer
Special measuring sensors are required for this purpose. Surface characteristics, de-sign of the measuring sensor, heat transfer, and environmental temperature influence the measurement result.

Note
Thermally conductive paste between the measuring sensor and surface can also in-crease measurement accuracy in some cases.

Cooling/evaporation
When measuring the air temperature, the probe should be dry, otherwise the temperature measured will be too low.

Response time
An adequate wait time must be observed for the measuring process before reading the measured value. The response time t90 describes the time in which the displayed measured value reached 90% of the end value.

Operation and maintenance

Operating and maintenance notices

Note

• The device and temperature probe must be handled with care and used by the technical data. Do not throw or strike.
• Plugs and sockets must be protected from soiling.
• If the device is stored at a temperature above 50 °C or is not used for an extended period, the batteries must be removed. Leaks from the batteries are avoided as a result.

Battery

Battery indicator
If the empty frame in the battery display blinks, the batteries are depleted and must be replaced. However, the device will still operate for a certain length of time. If the BAT display text appears in the main display, the battery voltage is no longer adequate for the operation of the device. The battery is fully depleted.

Changing battery

Danger! The danger of explosion!
Using damaged or unsuitable batteries can generate heat, which can cause the batteries to crack and possibly explode!

• Only use high-quality and suitable alkaline batteries!

Caution! Damage!
If the batteries have different charge levels, leaks and thus damage to the device can occur.

• Only use high-quality and suitable alkaline batteries!
• Do not use different types of batteries!
• Remove depleted batteries immediately and dispose of them at a suitable collection point.

Note
Unnecessary unscrewing endangers the protection against moisture and should therefore be avoided.

• Read the following handling instructions before replacing batteries and follow them step by step.
• If disregarded, the device could be damaged or the protection from moisture could be diminished.

1. Unscrews the Phillips screws (A)and remove the cover.
2. Carefully replace the two Mignon AA batteries (B). Ensure that the polarity is correct! It must be possible to insert the batteries in the correct position without using force.
3. The O-ring (C) must be undamaged, clean and positioned at the intended depth.
4. Fit the cover (D) on evenly. The O-ring must remain at the intended depth!
5. Tighten the Phillips screws (A).

Calibration and adjustment service
The purpose of the calibration is to verify the precision of the measuring device by comparing it with a traceable reference. Both ISO calibration certificates and DAkkS calibration certificates are available from Senseca.

Explanation

• The ISO standard 9001 is applied for the iso-calibration certificates.
• These certificates are affordable alternatives to the DAkkS calibration certificates and provide information on the traceable reference, a list of individual values, and documentation.
• The DAkkS calibration is based on DIN EN ISO/17025, and the accreditation basis is recognized worldwide. These certificates offer high-quality calibration and consistently high quality. The DAkkS calibration includes any necessary adjustment to minimize a deviation of the measuring device.
• The device is delivered with a test report. This confirms that the measuring device has been adjusted and tested, without making any statement about the accuracy of a temperature sensor.
• Only the manufacturer can check the basic settings and make corrections if necessary.
