MAINTENANCE
Low Battery Indicator
When the Mentor LCD begins to flash, it is
an indication the battery voltage is low and it
should be replaced or recharged (See
maintenance instructions for battery
replacement information).
WARNING: The Mentor should not be used
while a low battery condition is indicated.
During a low battery condition, the pressure
readings may not be within the operating
specifications and results may be erroneous.
Error Messages
If the Mentor displays an error message it
should be returned to Merit Medical for repair.
Er1 = Memory error detected
Er2 = General hardware/software error
detected
“OPr” = Pressure is not within pressure range.
i.e. +/- 300 mmHg.
Battery Replacement
The access panel for the battery compartment
is located on the back side of the Mentor.
Remove the battery cover using a small slotted
screwdriver and replace the battery with a 9
volt alkaline, non-rechargeable battery.
Please note: If the Mentor is not going to be
used for an extended length of time (30 days or
more), the battery should be removed until
reuse.
Cleaning
The outside surfaces of the Mentor may be
cleaned with a soft cloth dampened with water
or isopropyl alcohol.
Checking Mentor Calibration
Every six months the Mentor should be
checked for proper calibration. This can be
done by the following steps using a mercury
sphygmomanometer with a scale in mmHg
(millimeters of mercury).
1. Turn on and zero the Mentor Simulator/
Tester.
2. Connect a short length of pressure
monitoring tubing from the Mentor’s
Transducer Test Port luer fitting to the pressure
inlet on the mercury sphygmomanometer.
3. Pump the bulb on the sphygmomanometer
creating a pressure of 300 mmHg or as close as
possible and check that the mercury level is
fixed. If it is falling, check for tubing leaks.
4. Verify that the Mentor’s LCD Display reads the
same pressure as the sphygmomanometer to
within 1% or 1 mmHg, whichever is greater. If
the Mentor is out of calibration it should be
returned to Merit Medical for service. Please see
directions following for returning product.
