Activation of test (verification) mode
In test mode it is possible to achieve precise results within short measuring time.
For activation of Verification (Test) mode you must opening device and set up jumper on the connector (J)
contacts as shown in Figure 7.2.
Fig. 7.2. Test mode activation
For working in this mode, the calculator cannot be closed.
When the jumper “J” is set, output pulses are formed.
Ending of verification mode
Remove jumper “J” to leave test mode and return to normal mode.
Note:
In normal mode the jumper “J’ must be removed.
8. VERIFICATION
Metrological control of flow sensor parameters is performed according to requirements defined in EN 1434-5.
9. TRANSPORTATION AND STORAGE REQUIREMENTS
Requirements for safe transportation and storage of temperature and pressure sensors are
provided in relevant technical documentation.
Packed equipment may be transported in any type of covered vehicle. Equipment should be anchored
reliably to avoid shock and possibility to shift inside vehicle.
Equipment should be protected against mechanical damage and shock.
No aggressive chemical substances should be stored together because of corrosion hazard.
