Series 72 Manual page 1 1. Fundamental Features of Series 72 Series 72 Humidity and Temperature Meters detect relative Humidity and Temperature. For this purpose the probes - either fixed mounted or interchangeable ones - are equipped with a capacity type humidity sensor of very small mass. The temperature detection is done by a RTD of type Pt-1000, which is placed very close to the humidity sensor to avoid differences in temperature between the two sensors.
Series 72 Manual page 2 2.2. Setup for Operation The instrument is to be connected to main powers either by a connector or by using the terminals inside the housing. The correct voltage is marked on the type label you find on one side of the housing. Do not use voltages other than the marked one! Severe damage would be the result of applying the wrong voltage. If a type 72B. instrument with screw terminals is used, the cross section of your conductors should meet the dimensions of 0.5 up to 1.
Series 72 Manual page 3 done by turning the four fast mounting screws 90 degrees to the left with a screwdriver. The red coloured buttons are marked on the display - board with: 1) 2) 3) 4) "E" "M" " " " " = enter = mode = encrease = next decimal The two arrows are the only pushbuttons which have an "enhanced speed" function, which operates after pressing them for a time period of more than 1 second. In the "LIST" submenus the " "-button leads to the next, the " "-button to the previous display point.
Series 72 Manual page 4 This is a feature which enables the user, supplier and manufacturer - even after a malfunction - to analyse what has happened with the transmitter.
Series 72 Manual page 5 5.4. Data in "LIST" - "CONDAT" Submenu "CONDAT" displays all data, which describe the actual configuration of the transmitter. After chosing "CONDAT" and pressing "E", you will find the data as follows: 1) lower limit of Humidity range 2) upper limit of Humidity range 3) reaction at sensor break Hum. 4) lower limit of Temp. range 5) upper limit of Temp. range 6) reaction at sensor break Temp. 7) offset analog output Temp. low 8) offset analog output Temp.
Series 72 Manual page 6 F) = sensor oscillator R) = reference oscillator Finally the display shows the actual pressure factor, marked by "PRESS". This factor is used to calculate humidity values at atmospheric pressures, if measurement occurs at other pressure conditions. The calibration data display may be left by pressing "E", the program then jumps back to "CALDAT". 6.Calibration 6.1. General Notes about Calibration Standards There is a lack of international standards for rel.
Series 72 Manual page 7 To assure the easiest handling and highest accuracy, the solutions are enclosed in glass ampoules, which should be opened only before usage. Opening is simplified by the weakened middle part of the ampoules. Once opened the solutions may catch humidity from or give humidity to their environment - so the time of usage is restricted and they should be used for one calibration only. 6.4. Calibration Chamber The calibration chambers we are supplying under No.
Series 72 Manual page 8 Ensure that the calibration chamber faces downwards, to avoid direct contact of the solution with the sensor. Before inserting the bottom into the chamber, unscrew the chamber slightly, to help escaping air, when you close the chamber. Tighten the chamber again after closing! 7. Program "CALIB" 7.1. Password Protection To protect series 72 instruments against unwanted changes of their calibration, this part of the program is protected by a password.
Series 72 Manual page 9 1) A calibration with saturated LiCl-solution of 11.3% will replace the former 10%-value. 2) A calibration with saturated NaCl-solution of 73.6% will not replace the two former values at 65% and 80%. 7.3. Entering "CALIB" From normal measuring mode you enter the main program area by pressing "E". The display now shows "LIST". Pressing "M" now switches over to "CALIB" and the first line of the display shows "0000" with a flashing first digit.
Series 72 Manual page 10 7.5. Submenu "DELETE" The submenu "DELETE" allows you to cancel an old calibration totally, before recalibrating a probe. This procedure must be done, when tests show a deviation of standards of more than 5% rel. Humidity. In this case, check the sensor by visual inspection. If no mechanical defects occured, and no layer of dust or other contamination is found, a new calibration is required. To erase all calibration points hit "E" when "DELETE" is in the display.
Series 72 Manual page 11 8. Configuration of Series 72 Transmitters 8.1. Password Protection As in "CALIB", the program "CONFIG" has password protection to avoid unwanted changes of configuration. The same 4-digit number is used as in "CALIB". 8.2. Possible Configurations The digital electronics of type 72 instruments allow the user to fully customize the display and outputs. We tried to do this in a practical manner to adapt the instrument to a variety of applications.
Series 72 Manual page 12 8.6. Submenu "ANALOG" This part of the program is used to define the ranges of temperature and humidity, which correspond to the analog outputs. Furthermore this menu may adjust offsets in the analog outputs. This is helpful to compensate for any discrepancies between the series 72 instrument and any other device coupled to the output. 8.6.1.
Series 72 Manual page 13 8.6.5. Limits of Temperature Range In the same way you may now change temperature limits and reaction of analog output, if a break in the sensor line of Pt-1000 occurs. The display will now show "T out" instead of "H out" or "T err" instead of "H err", but the change of values is the same as points 7.6.2, 7.6.3 and 7.6.4. If these parts of the program are done, the "RANGE" menu ends.
Series 72 Manual page 14 9.1.1. Protocol 1 Transmission of datas will occure every second. Each string consists of 16 ASCII-codes, configurated as follws: STX DIM SPACE HUMIDITY SPACE TEMPERATURE CR LF BYTES 1 1 1 5 1 5 1 1 DECIMAL 2 s.b. 32 s.b. 32 13 13 10 HEXADECIMAL 2 s.b. 20 s.b. 20 s.b. OD OA DIM: The dimension will be sent as ASCII-Code.
Series 72 Manual page 15 00809 is to read 80.9 %RH (or other dimension) 9.2. MODUS 2: Software Handshake, controlled by Host It is necessary that: Signal CTS is connected to +12V. (Bridge RTS-CTS) 9.2.1. Control of stand-alone Transmitter (XON/XOFF-Handshake) For this, the address of the transmitter must be "0" The following ASCII-codes will cause actions: XON: XOFF: CAN: P: (17dez,11hex) String as in Mode 1 will be send. (19dez,13hex) ends data transfer after next Byte and deactivates digital output.
Series 72 Manual O: page 16 (79dez,4Fhex) Output: opens the ring, sends a string of datas (with address) according to protocol 2 (s.b.). closes the ring thereafter and so enables further transmissions. 9.2.3. Protocol 2: A string of 19-ASCII codes is transmitted with the following content: STX ADR SPACE DIM SPACE HUMI. SPACE TEMP. CR LF BYTES 1 2 1 1 1 5 1 5 1 1 DECIMAL 2 s.b. 32 s.b. 32 s.b. 32 s.b. 13 10 HEXADECIMAL 2 s.b. 20 s.b. 20 s.b. 20 s.b.
Series 72 Manual page 17 Humidity: Again this value is sent with resolution of 1/10 %RH (or any other dimension) without decimal point as ASCII-code. The highest decimal is sent first. Dewpoints may have negative values which are transmitted as their dualcomplement (16-Bit), without sign, in the same way as negative temperatures. Example: 00809 is to read 80.9 %RH (or other dimension) 9.3.
Series 72 Manual page 18 message (flashing) will be displayed in the lower line. This message shows as "err...." where "..." is a three digit number. This number gives information about the nature of the malfunction detected: 001 = No Humidity frequency = Defect of Humidity sensor. 002 = No reference frequency = Mostly caused by cable break. 004 = Temperature < -50,5 °C = Short circuited Pt-1000 005 = 001 and 004 are both detected. 006 = 002 and 004 are both detected.
Series 72 Manual page 19 11.1 Direct Contact with Liquids Avoid in any case direct contact between the humidity sensor and any liquid. The sensor may only detect the humidity in the atmosphere over the surface of a liquid or a solid material. Even if the sensor will not be changed in his characteristic by direct contact with water and will measure correct values after being dryed, you should avoid immersion or condensation.
Series 72 Manual page 20 11.4 Protection of Transmitter Electronics To give highest protection against the surrounding atmosphere, our transmitter housings are according to IP 65. Avoid atmospheres of more then 80 %RH, as condensation could occur with rapid temperature changes. 11.5 Influence of Temperature on Humidity To detect rel.

Humidity displayed by HYGROMESS Instruments. 11.7 Measurements under Pressure or Vaccuum All probes can be used at pressures of 0,9 to 1,3 bar. Only special probes with a glas feed-through (which predicts SS - 316 tube material) may be used under pressures of 0,03 to 30 bar. As rel. Humidity is directly proportional to the pressure (f.E.
