Troubleshooting Tips
If an issue is encountered while using the Versa Star Pro meter with measurement modules,
ensure the correct power adapter is being used and try power cycling the meter: disconnect the
power adapter from the meter, wait 15 seconds and reconnect the power adapter to the meter.
Perform a factory reset on the meter; refer to the
Diagnostics Menu
section for instructions.
Meter Issue
Recommended Action
The meter shows the
message: Module not
detected … Plug in module
to start measurement.
Insert at least one module into an open channel on the meter, once the
module is detected, the meter will display the main measurement screen
for that measurement module.
The channel ID icon does not
show that a measurement
module is connected.
Check that the module is properly connected with an open channel on
the meter. Remove the module and reinsert it into a different channel.
Perform a factor reset on the meter; refer to the
Diagnostics Menu
section for instructions.
The measurement value is
flashing 9999 and displaying
Over Range or Under
Range
The measurement is outside the allowable measurement range. Make
sure the electrode or probe is fully connected with the measurement
module and verify the correct channel is shown on the meter display.
The meter locks up while
connected to a computer via
the USB cable.
Disconnect the USB cable from the meter and computer and then
disconnect and reconnect the power adapter from the meter. Reestablish
the meter and computer USB connection.
The measurement value
freezes and will not change.
The read type is set to Auto-Read mode (AR icon shown on the display).
Press the measure (esc) key to take a new measurement or use the
setup menu to change the read type to continuous.
The meter display goes
blank, shows random lines or
intermittently freezes.
Ensure the correct power supply for the Versa Star Pro meter is being
used. This power supply is different from the one supplied with other
Thermo Scientific Orion meters. The use of a surge protector or
uninterrupted power supply (UPS) is also recommended. Perform a
factor reset on the meter; refer to the
Diagnostics Menu
section for
instructions.
The meter does not
automatically recognize the
pH buffer during calibration.
Verify the correct buffer set was selected in the setup menu. The meter
uses raw mV readings to recognize the buffer. As the electrode ages or
becomes dirty, its mV readings will drift. Check the buffers and clean the
electrode according to the instructions in the electrode manual.
The meter does not
recognize the conductivity
standard during calibration.
Verify that the correct nominal cell constant is entered in the setup menu
for the conductivity probe being calibrated. The cell constant is usually
printed on the cable of the conductivity probe. Verify that the conductivity
standard is one that can be automatically recognized by the meter.
Recalibrate the conductivity probe using new conductivity standard.
The meter does not
recognize an RDO optical or
polarographic DO probe.
Make sure the DO probe is fully connected with the measurement
module and verify the correct channel is shown on the meter display.
Wait about 15 seconds after connecting a DO probe for the meter to
recognize the DO probe type. Press the measure (esc) key to initiate a
new measurement and update the meter display.
