How to fix Kamstrup MULTICAL 403 Measuring Instruments with no display function?
If your Kamstrup Measuring Instruments display is blank, the issue is likely a missing power supply. Try changing the battery or checking the mains supply to ensure it provides 3.6 VDC.
Why is my Kamstrup Measuring Instruments temperature reading incorrect?
An incorrect temperature reading in your Kamstrup Measuring Instruments may be due to a defective temperature sensor or insufficient installation. Replace the sensor pair and check the installation.
What to do if Kamstrup MULTICAL 403 shows no energy or volume accumulation?
If your Kamstrup Measuring Instruments isn't accumulating energy or volume, check the error code indicated by the info code. If “INFO” is 00000000, ensure the flow direction matches the arrow on the flow sensor. If “INFO” is xXxxxxxx, xxXxxxxx or xXXxxxxx, consult the ”INFO” overview and inspect the temperature sensors; replace them if defective.
Why does my Kamstrup MULTICAL 403 accumulate volume but not energy?
If your Kamstrup Measuring Instruments accumulates volume but not energy, it could be due to interchanged inlet and outlet sensors during installation or connection. Ensure the sensors are mounted correctly. Alternatively, the heat/cooling cut-off may be configured at too low a value. Reconfigure to a suitable value, or set it to 250 °C to disconnect the cut-off function.
How to improve low temperature or energy readings on Kamstrup Measuring Instruments?
If your Kamstrup Measuring Instruments shows a slightly low temperature or energy accumulation, it might be due to poor thermic sensor contact, heat dissipation, or too short sensor pockets. Ensure the sensors are pushed to the bottom of the sensor pockets, insulate the sensor pockets, or replace them with longer pockets.
