Why does my Vaisala Test Equipment MI70 power off by itself?
The MI70 might be powering off by itself because: * The Auto Power Off feature is enabled. You can turn off this feature from the Settings - User interface menu if you want to. * The battery of the MI70 has run out. Recharge the battery or change the non-chargeable batteries (if used).
What to do if Vaisala Test Equipment MI70 displays "Switch off power and connect probe"?
If the message "Switch off power and connect probe" appears on the MI70 display, it could be due to: * Measurement instruments not connected. Turn off MI70 and connect PTB330 and/or HMP155. * Loose cable connection. Turn off MI70 and tighten the connectors. * Incorrect cable. Check that you are using the spiral cable 223235SP between MI70 and PTB330, and cable 221801 between MI70 and HMP155.
What does "Pressure out of valid range" mean on Vaisala PTB330TS PTB330?
The message "Pressure out of valid range" appearing when PTB330 is connected means that the pressure measured by the barometer is outside the specified measurement range 500 ... 1100 hPa. To resolve this, do not operate the barometer outside the measurement range.
Why is Vaisala PTB330TS Test Equipment HMP155 measuring incorrect humidity?
If the HMP155 is measuring incorrect humidity readings, the possible causes are: * Condensation has formed on the sensor. Activate the chemical purge function to dry it. * There may be a temperature difference between the HMP155 and the measurement environment. Let the temperature stabilize.
Why does Vaisala PTB330TS MI70 display dashes instead of readings?
If the measurement reading on the MI70 display shows dashes "----" instead of measured values, it could be because: * You have selected P (pressure trend and tendency) as 3h one of the measured quantities. Wait patiently, and make sure the Auto Power Off feature is disabled in the Settings - User interface menu. * The measurement instrument has been disconnected. Turn off the MI70 and reconnect it.
What to do for "Operating voltage out of range" on Vaisala PTB330TS PTB330?
If the message "Operating voltage out of range" appears when PTB330 is connected and powered by an external power source, it indicates that the supply voltage of the barometer is outside the correct range. Change the supply voltage to 10 ... 35 VDC.
Why does Vaisala PTB330TS PTB330 serial output show asterisks instead of values?
If you see asterisk characters (****) instead of measured values when outputting measurement messages on the PTB330 serial line, it could be due to: * You have selected P (pressure trend and tendency) as 3h one of the quantities in the measurement message. Wait patiently, and make sure the Auto Power Off feature is disabled in the Settings - User interface menu of the MI70 indicator. * There may be a problem with the measurement. Check the display of the MI70 for messages.
What does "Difference between pressure transducers too large" mean on Vaisala PTB330TS PTB330?
If the message "Difference between pressure transducers too large" appears when PTB330 is connected and more than one module is used, it could be because: * All barometer modules may not be measuring the same pressure. Open the barometer and check the tubing to the pressure input connector. * The allowed pressure difference may be set too low. Connect to the service port of the barometer and use the DPMAX command to check the value.
How to fix "Add-on module connection failure" on Vaisala PTB330TS Test Equipment PTB330?
If the message "Add-on module 1/2/3 connection failure" appears when PTB330 is connected, it is likely due to a loose connection of an add-on module. To fix this, turn off the power, and open the barometer. Check that the ribbon cables of the modules are securely connected. Close the barometer and turn on the power.
What does "Device internal temperature out of range" mean for Vaisala PTB330TS Test Equipment PTB330?
The message "Device internal temperature out of range" appearing when PTB330 is connected indicates that the barometer is either too hot or too cold. Ensure that the operating temperature is within the valid range.
