4. Refill the electrode and make sure that the fill solution is making contact between the
black cone and the plastic shell at the bottom of the electrode. If it is not making
contact at all points, drain the electrode again and refill.
5.
With the meter off
, connect the electrode to the BNC connector labeled “
Electrode
”
on the back of the
L2000
DXT
Analyzer and check electrode output.
6. To check the electrode, turn the Analyzer on by pressing the
ON
Button on the back
panel of the instrument. From the
START SCREEN
press
ENTER
to open the
MAIN MENU
. At the
MAIN MENU
, press
DIAG
to open the
DIAGNOSTICS
screen. This display:
will indicate the current system information and then continuously update the
electrode output in millivolts (mV). Place the electrode in fresh RINSE solution,
gently swirl the solution with the electrode and allow to equilibrate. The electrode
output should reach 140 mV or greater within 1 minute. If the electrode output does
not reach at least 140 mV by the time the 2 minute buzzer sounds, empty the RINSE
solution and refill with fresh RINSE solution. If this does not improve the electrode
output, drain the electrode, refill it with filling solution and check the output again.
NOTE: When setting up the
L2000
DXT
after the unit and/or electrode has been in
storage or is brought from a colder/warmer environment, it is important to allow both
the unit and the electrode to equilibrate for as long as possible. It could take up to an
hour for the electrode to equilibrate. Once the output is greater than 140 mV, the
electrode is functioning correctly and it is safe to proceed with measurements. If the
electrode output does not reach 140 mV, see under
Troubleshooting
for remedies.
NOTE: The update rate for the
DIAGNOSTICS
screen is 10-20 seconds, any keys pressed will
not register until the end of the current measurement cycle. Therefore, to exit the
DIAGNOSTICS
screen, the
BACK
button must be pressed until the meter registers the input.
