Just bought a new Milwaukee ph meter and trying to calibrate it.

The instructions say to immerse the electrode tip into a new sachet of ph 7 calibration solution and allow the reading to stabilize.
Adjust the OFFSET calibration trimmer (on the front) to display 7.0 ph.
Open a new sachet of ph 4 and immerse the electrode tip into the ph 4 sachet and allow the reading to stabilize.
Adjust the SLOPE calibration trimmer (on the rear) to display 4.0 ph.

BUT I DON'T HAVE ANY 4 SOLUTION, I ONLY HAVE 7 AND 10. CAN I STILL CALIBRATE IT WITH 7 AND 10? AND WHICH DO I USE FOR THE FRONT AND WHICH FOR THE BACK OR DOES IT MATTER?

THANKS,
BILLY

You would use 4.0 solution for freshwater applications.
Use the 7.0 solution for the offset and then use the 10.0 solution for the slope.
