Info

7. Operation• Menu item "Measuring range"The measuring range can be freely selected within the limits 0-500µg/Nm³ (separately for both current outputs). A message is output if theupper end value for the measuring range of the first output is exceeded.Current from 4 to 20 mA is available (in parallel for both outputs) at thecorresponding terminals (customer interface X3).The second output is optional.• Menu item "Calibration"The calibration parameters can be directly changed after entering a validpassword.A calibration process is triggered by pressing theCalibration)key. (see• Menu item "Threshold value"The threshold value is freely definable and generates a message ifexceeded.• Menu item "Record Parameter"(Optional for service purposes)• Menu item "Integration time"The output of the concentration measuring value can be freed fromundesirable peaks through average value formation over a variable timeperiod.Attention! The average value formation is also active during calibration.• Menu item "Service request”This displays in how many weeks the next instruction to request aservice visit for device maintenance will occur.• Zero gas concentration” menu item”If the measuring signal (!) exceeds the specified concentration value [µg]the device is switched to zero gas via the bypass. When the specifiedTime [seconds] has elapsed, the device reverts to measuring gas.Entering 0 (zero) seconds for the time deactivates this function.60 HM 1400 TRX
7. Operation7.3 Zero offset (manual)Figure 7.6 The zero offset determination started manuallyThe zero offset determination can be started manually.Attention! If the device is currently in measuring mode, triggering a zero offsetmeasurement will result in an interruption of measuring mode.After triggering the zero offset measurement by pressing the key, acurrent measuring value ("zero" measuring value) will appear in the display inμg/Nm³. To ensure that the "zero" measuring value is not falsified by anyresidual quantities of mercury in the suction intake, you must wait a fewminutes for the value to stabilise before accepting it.After pressing the key, the zero offset measuring value in μg/Nm³ isstored as offset. The display changes back to the standard operating screenafter approx. 2 seconds.HM 1400 TRX 61
