    Problem: T he meter did not accept the change I made in the setup menu. Solution: A fter making a change in the setup menu, press until the arrow icon points to the top line (confirms the change) and then press to save the change and return to the measurement mode. Problem: How do I abort a calibration? Solution: P ress and hold to abort any meter operation and return to the measurement mode. Problem: The printout is a string of numbers and units with commas. Solution: T he output format in the setup menu is set to the computer output or the printer baud rate is set incorrectly in the setup menu. Change the output format to the printer output in the setup menu. Change the baud rate to the correct value for the printer that is being used. Problem: When I press the stirrer button, the stirrer doesn’t work. Solution: T he current stirrer setting is off. Set the speed to 1 through 7 in the setup menu.

  • Page 52 ISE Troubleshooting Problem: It takes several minutes for the readings to stabilize during a calibration. Solution: The concentration range in the setup menu is set to low. Change the concentration range to high. The ISE resolution is set to 3 digits in the setup menu. Change the ISE resolution to 2 digits for faster stabilization of the readings. Problem: When I use the automatic blank correction setting and calibrate an ISE, the meter gives a slope that is too low or cannot be manually checked. Solution: Turn the automatic blank correction setting off in the setup menu. LogR Troubleshooting Problem: The meter does not recognize the ATC probe during calibration. Solution: Verify that the ATC probe is connected to the meter. Press and hold to abort any meter operation and return to the measurement mode. Change the temperature reading and compensation setting to ATC in the setup menu. If the meter defaults to , verify the connection of the ATC probe by disconnecting and securely reconnecting the ATC probe. Problem: The temperature reading and compensation setting (third line of the display) automatically changes to AtC or mAn when in relative mV or ISE measurement parameters. Thermo Scientific Orion Star LogR™ Meter User Guide...
  • Page 53 Solution: The LogR technology is only available for pH and mV measurements. When reading relative mV (RmV) or ISE values, the meter switches to , or if an ATC probe is not connected. Selecting the pH or mV measurement parameter will automatically switch the meter back to LogR, if that was the setting prior to ISE or RmV readings. Problem: L ogR temperature value is not within the expected range. Solution: Verify that the LogR calibration has been completed. If the temperature reading and compensation setting was not set to LogR, the LogR setting was not calibrated. The first screen when starting the temperature calibration shows the setting. Problem: T he resistance display shows “--------” Solution: The resistance input is over 6000 Mohms. This resistance value is normal for a new electrode not yet placed into a solution. Prepare the new electrode for testing and place into a solution. Assistance After troubleshooting all components of your measurement system, contact Technical Support.
