MULTICAL® 302
The coupling must not be pushed further down
than the first knurling.
No matter where the direct sensor is installed,
it is very important that you observe the tole-
rances stated in the drawing to the left. If not,
the O-ring may not provide correct sealing.

3 Information codes "INFO"
MULTICAL® 302 constantly monitors a number of important functions. If there is a serious error in
the measuring system or installation, a flashing "INFO" is displayed, and an info code can be read
by activating the push-button until the measuring unit displays "INFO". The info code is only shown
if an error has occurred, unless the meter is configured for "static info codes".

Temperature sensor T2 outside measuring range
< 32 secs.
8
Temperature sensor T1 outside measuring range
< 32 secs.
32
Temperature difference has wrong polarity
< 32 secs. and 0.05 m

128
Supply voltage too low
< 10 secs.
16
Flow sensor with weak signal or air

If more than one info code appears at a time, the sum of info codes is displayed. If e.g. both
temperature sensors are outside measuring range, info code 12 (info codes 4+8) is displayed.
Info codes 4 and 8 are set when the temperature falls below 0.00 °C or exceeds 155.00 °C. Info
codes 4 and 8 are also set for short-circuited and disconnected sensors.
Note:
If Info = 4 or 8, the meter's energy calculation and volume accumulation stop.
