DIAGNOS – Enters the diagnostic function. Press the Up Arrow Keypad button to toggle between the monitor’s two diagnostic screens. Refer to Working with the DIAGNOS Function (Page 21).
SILENCE – Used to enter a length of time for which the internal audible alarm and the external alarm are turned OFF when the front panel SILENCE button is pressed. The factory default is 300 seconds (5 minutes). If the cause of the alarm/fault has not been cleared at the end of this time period, the internal audible alarm and the external alarm device are reactivated. Use the Keypad to enter the desired time period, and then press ENTER to save that value and return to the previous screen.
ZONETEMP – Used to enter the temperature of the area being monitored in °C, thus giving a more accurate ppm reading. The factory default is 25°C. Use the Keypad to enter the desired temperature, and then press ENTER to save that value and return to the previous screen.
SQUELCH – Sets a value of between 0.0 and 99.9 ppm that prevents the display of measurements below that value. Factory default is 0 ppm. For example, if the squelch setting is set to 50 ppm, then the monitor will not display measurements that are below that value. Use the Keypad to enter the desired value, and then press ENTER to save that value and return to the previous screen.
CAL – Used to change a calibration factor for a specific gas. This function is to be used ONLY with instructions from a Bacharach Service Center. Factory default is 1.000.
LOG INT – Sets the interval at which measurements are logged to memory from 1 to 9999 minutes. Factory default is 10 minutes. Note that the logged measurements can be viewed using the PPM LOG function. Use the Keypad to enter the desired value, and then press ENTER to save that value and return to the previous screen.
LOOP – Use to adjust the loop factor of the
To facilitate loop zero and span checking, note that when the LOOP function is selected the loop output is set to 20 mA, and upon exiting this function the loop output is set to 4 mA.
