SonoMeter 40
This instruction is designed for the ultrasonic energy meter SonoMeter 40 for flow and energy
verification and calibration.
The test mode can be activated in one of the following ways:
The test mode is activated by the meter's control button according to the following procedure:
- long press the button, on the meter's LCD select page „INF";
- short press the button, select „TEST on Wh" (when it is necessary to activate the energy pulse
output via the optical interface) or „TEST On m³" (when it is necessary to activate the volume pulse
output via the optical interface);
- long press the button, open the 4- digits security password input window:
- short press the button, select digit in the first position, after that long press the button and go to
the next position;
- after selecting the digit in the fourth position, long press the button, the massage „PASS" appears
briefly (when the password entered correctly) and the meter switches to test mode – the sign
„TEST" appears;
- if the password was entered incorrectly, the message „FAIL" appears briefly and the meter returns
to the operating mode, and the procedure for turning on the test mode must be repeated initially;
- the password value is fixed: 0001.
NOTE: when the test mode is activated by the button, the volume and energy accumulated in
the test mode are added to the meter's energy and volume readings in operating mode (after
turning off the test mode).
Remove the breakable partition „SERVICE" (1) on the back of the calculator or open the calculator box
by removing the breakable partitions "LOCK" (2).
By short-circuiting the contacts „SERVICE", the SERVICE mode is activated, symbol „<->" and sign
