What to do if my Chauvin Arnoux Measuring Instruments meter doesn’t count?
If your Chauvin Arnoux Measuring Instruments meter isn't counting, verify if the red consumption LED is flashing. Also, check the load current, ensuring it's at least 20 mA. The problem may be that there is no load connected to the meter or the load is too less.
Why the red LED doesn't flash on my Chauvin Arnoux Measuring Instruments?
If the red LED on your Chauvin Arnoux Measuring Instruments isn't flashing, it could be due to no load or a very low load connected to the meter. To fix this, connect a load to the meter and check if the current value is at least 20 mA.
How to fix a Chauvin Arnoux ULYS MD45-M meter that is not turning on?
If your Chauvin Arnoux Measuring Instruments meter isn’t turning on and the screen is off, check the 230 Vac voltage between terminals 1 and 4. Also, verify that the protection device hasn't been triggered. The cause may be that there is no voltage on the line or the protection device is triggered.
What to do if there is no pulse output from Chauvin Arnoux ULYS MD45-M Measuring Instruments?
If there's no pulse output from your Chauvin Arnoux Measuring Instruments, use a voltmeter to check that the external voltage source (Ui) is 5-27V DC. Also, check if the connection is correct: the 5-27V DC should be connected to the collector connection (pin 20+) and the signal wire (S) to the emitter connection (pin 21-). The issue might be because the pulse output is not supplied with DC power, not connected correctly, or the polarity is wrong.
Why is the pulse output rate wrong on my Chauvin Arnoux ULYS MD45-M?
If the pulse output rate is wrong on your Chauvin Arnoux Measuring Instruments, set the pulse output rate correctly in program mode 3 or use the infrared eye which can be bought separately. The issue is probably because the pulse rate is not setting correctly in the Program mode 3.
