What to do if the SGE eVol xr Analytical Instruments display turns off completely?
If the display turns off completely, it is likely due to a dead battery. Charge the batteries using a power cord or charging stand.
What to do if SGE eVol xr Analytical Instruments dispense results are inaccurate?
If you're experiencing inaccurate dispense results, it could be due to the syringe being incorrectly attached. Refit the syringe. Alternatively, the syringe might not be correctly calibrated; in this case, follow the re-calibration instructions.
Why is my SGE eVol xr Analytical Instruments not dispensing or aspirating?
If your device is not dispensing or aspirating, it could be due to several reasons. The plunger may be jammed or damaged; remove the syringe, inspect the plunger function manually, and if undamaged, replace the syringe and re-test. Alternatively, the plunger might not be connected correctly; if damaged, replace the plunger. Finally, the motor may not be running; check the battery charge level.
What to do if pressing RUN on SGE eVol xr Analytical Instruments shows a ‘Battery Low’ message?
If a ‘Battery Low’ message appears on the Run screen when pressing RUN, it indicates a low battery. Re-charge the battery to resume operation.
Why is the touch wheel response erratic and uncontrollable on my SGE Analytical Instruments?
If the touch wheel response is erratic and uncontrollable, it could be because a finger was on the touch wheel when the device was turned on. Reset the device without touching the touch wheel during reset. Alternatively, the sensitivity setting may not be set correctly; adjust the touch wheel sensitivity using Toolbox, Preferences, Touch Wheel.
What to do if I get an error message ‘Home Found’ or ‘Home Not Found’ on my SGE Analytical Instruments?
The error message ‘Home Found’ or ‘Home Not Found’ indicates too much friction was encountered during operation. Reset the device. It could also indicate a possible motor failure; remove the syringe, inspect the plunger function manually, and if undamaged, replace the syringe and re-test.
How to fix inaccurate dispensing with certain liquids in SGE eVol xr Analytical Instruments?
If you're experiencing inaccurate dispensing with certain liquids, it could be due to unsuitable calibration. Re-calibrate with the liquids in question. Also, incorrect aspirate and dispense speeds can cause this issue. Adjust aspiration and dispense speed depending on the liquid; high viscosity liquids will require slower speeds.
What to do if the plunger de-couples from plunger drive in SGE eVol xr?
If the plunger de-couples from the plunger drive, it could be because certain liquids can affect the plunger tip material and increase the force required to drive the plunger. Manually flush the syringe with water. Also, the syringe plunger tip can sometimes stick to the glass if left for long periods without use; manually cycle the syringe plunger.
Why is the battery charging indicator not pulsing on the SGE Analytical Instruments?
If the battery charging indicator is not pulsing while on the stand, and the unit does not turn on when placed on the charging stand, check that both charge stand conductor pins are at the same height. Also, make sure the charger is plugged in.
Why does the motor sound rough and aspiration is very slow on my SGE eVol xr Analytical Instruments?
If the motor sounds rough and aspiration is very slow, verify the speed setting. The slowest speed setting normally causes the motor to run slowly and louder than normal.
