DIRECTIONS: Identify the following steps in operating a PH meter. Write A if the step is for Preparing for Calibration, B for Calibrating PH meter and C for Using PH meter. Write your answer on the space provided before the number. 1. Place batteries on your pH meter then turn it on and allow to warm up for 30 minutes, (but eck your pH meter's operating manual for exact time). 2. Place your electrode in the buffer of 7 and begin reading allow until it is stabilized. 3. Once reading has stabilized, press the measure button.
