1. INTRODUCTION

Instruments by Jörg Kachelmann

Jörg Kachelmann, meteorologist and founder of Meteomedia AG, revolutionised weather 
reports in the early 90ies with a new type of media presentation and the high quality of his local 
weather forecasts.

Today Meteomedia is one of the leading weather services in Europe and, with its own Severe 
Weather Centres in Switzerland and in Germany, among other things, specialist for modern 
early warning systems for extreme weather conditions.

The core of the company is the private weather measurement network. It is one of the biggest 
measurement networks in Europe.

With "Instruments by Jörg Kachelmann" Irox, market leader in the manufacturing of measuring 
devices, and Jörg Kachelmann have developed a joint product that convinces with its high 
quality measurements, simple handling and elegant design.

Weather forecasts by Jörg Kachelmann: www .meteocentrale.ch       

The JKTG-4R is a high-quality thermo/hygrometer that gives you the absolutely unique feature 
of choosing between three different max/min memory functions. The recording is done 
independently for each of the 6 channels in total. The individual scanning of the 5 radio
sensors also makes operation transparent and calculable.  

Please read the instructions carefully. They contain some useful and interesting information that 
go beyond a mere explanation of how to operate the device.     

2. OPERATING ELEMENTS

2.1 LCD DISPLAY

All functions are depicted on the liquid crystal display (LCD) in 3 windows. 

Full-segment display

 

Radio channels 1-5: 
- current measurement of the selected channel (=radio probe)
- memory values min/max of the selected channel
- battery status of the sender displayed

Comfort Zone: 
- display of the comfort status of the measurement of the indoor thermo/hygrometer

Indoor thermo/hygro     : 
- temperature and relative air humidity of the display device (measures at the location where the 
  device is used)    
- memory values min/max of the indoor thermo/hygrometer
- battery status of the display device     

2.2 KEYS / SWITCH / BATTERY COMPARTMENT

Rear view

(1    2     3     4     5     1    etc) 

°C/°F

Changes the unit of temperature in the display from °C to °F or vice versa

MEMORY RESET

Hold pressed for 3 seconds: Resets all memories (IN and CH1 ... CH5). The new recording 

  now begins depending on the setting of the MIN-MAX switch

CH 

(=CHANNEL)

- Press briefly: changes to display of the next channel

 
- Hold pressed for 3 seconds. For the radio channel active on the display (CH1 .... CH5), 
  a sender search is started. The three waves above the CH flash during the search process. 
  Only the sender of the channel displayed is searched for; the others remain unaffected.

T/H SET

For the IN measurement, the MIN/MAX values of the temperature or the relative air humidity 

  are displayed below the current value. With this key, you can have the temperature or hygro 
  memory displayed.

MIN-MAX

The MIN/MAX memory is managed and recorded depending on the setting. The setting applies 
for all 6 channels 

 

   

 

Pos. 1: 

PERM - 

From the last MEMORY RESET, the MIN/MAX recordings after the function 

            “drag indicator” are recorded. This recording is "PERMANENT", i.e. a new recording 
            does not start until after a new MEMORY reset.

Pos. 2: 

24 Hr - 

If you choose this option, the MIN/MAX values for the last 24-28 hours in each 

            case are recorded. After expiry of this period, the MIN/MAX values that are older than 
            24-28 hours are removed from the memory. As soon as you have selected this option, 
            we recommend that you start the memory recording in a defined way with a 
            MEMORY RESET. This then starts a recording that triggers internally an elaborate 
            calculation and recording. The MIN/MAX values are administered here in blocks of four 
            hours.
            Example: You want to be able to read the MIN/MAX values of the last 24-28 hours at all 
            times. Irrespective of when you look at the display, you will always see the extreme 
            values of the last 24-28 hours. Older recordings are deleted in the process. 

Pos. 3: 

DAY- 

If you select this option, the MIN/MAX values are recorded for 24 hours in each 

            case. You are free to choose when the recording should begin. The start is determined 
            by a MEMORY RESET and after 24 hours, the memory is automatically reset and a new 
            recording begins. Example: You want to be able to read the MIN/MAX values of the last 
            24 hours in each case at 8 p.m. You therefore carry out a MEMORY RESET at 8 p.m. 
            With this RESET, the clock begins to tick internally and this automatically resets the 
            memory after 24 hours and starts a new recording.                   

 

 

 

   

Battery compartment

2 x 1.5 batteries of the size AM-4 resp. “AAA”
To open: slide lid in the direction of the arrow (indicated on the lid) after the stand has been 
removed.  

3. PUTTING INTO OPERATION

1. Put all radio sensors that you want to use into operation and place these in close proximity 
    (1-2 metres) to the reception device.

2. Open the battery compartment of the display device and remove all insulation strips. If no 
    batteries are in the device, insert the 2 batteries (UM-3 or ‘AA’ 1.5 V) in the 

correct polarity.

3. Now close the battery compartment.

4. Directly after the activation of the batteries, all segments are displayed for a few seconds on 
    the display. The JKTG-4R then begins with the search of available sensors on all 5 channels.

5. As soon as the sensor is displayed correctly (see ‘Reception status’ in Chap., 4), you can set 
    up the sensor in the place where you want to effectively measure the outdoor temperature. 
    Under the most ideal conditions, this can be up to 30 m away. In reality, however, this is often 
    less. In the event of problems, try out other places, and do so both for the sensor and for the 
    display device. The radio sensor is weatherproof. Nevertheless, please place the sensor 
    where possible in the dry and at any rate in the shade.

6. If you would like to display further sensors on the reception device, you can purchase these 
    from shops. For outdoor use, we recommend weatherproof sensors. If you would like to 
    display other interior spaces, the sensor  JKR-1 from the ‘Instruments by Jörg Kachelmann’ 
    range is available in the same design as  that of the display device and also has a large 
    display.               

The unit is in searching mode.

Temperature readings are
securely registered.

No signals.

4. RADIO THERMOMETER 

The operation of the radio sensor supplied with the device is easy:

- Open battery compartment
- Select channel
- Activate batteries (i.e. remove insulation strip) or insert batteries (please make sure that the 
  polarity is correct!)
- Close battery compartment again (please ensure that it is tightly closed!)

Other Irox radio sensors that are compatible with the JKTG-4R:
3 channels (can be used on the channels, 1, 2 or 3) : HTS12C, HTS33, HTS13*, HTC13
5 channels (can be used on all 5 channels): HTS55, JKR-1

(*HTS13 is included in the scope of delivery of the JKTG-4R and can be used on the 
channels 1-3)

With the sensors with thermo and hygrometer, simply only the temperature is displayed on the 
JKTG-4R. 

Reception status display

The wave symbol indicates the status of the signal reception of the channel displayed.
