If the unit detects excessive current (greater than 4.5 amps) the current overload error
will be displayed.
Action: The output will be disabled until the unit is disconnected from the electric supply
to reset the error. When the error occurs the unit will read:

caliBratinG tHe pH sensor

The apcepH1 uses a high quality pH
sensor, but all pH sensors can go out of
calibration due to debris accumulating
on the sensor surface or other factors.
The APCEPH1 has a simple process to
recalibrate the pH sensor.
The temperature sensor NEVER requires
calibration.
Note: It is critical to FIRST calibrate the pH
sensor to 7.0 pH. After Cal 7.0 is complete, you
can calibrate to 4.0 pH.
1. Shut off water circulating pump.
Remove the pH sensor from the pH
sampling assembly.
2. Rinse the tip of the pH sensor
with clean water to remove any
accumulated dirt or debris.
3. Shake or wipe excess water from the
sensor.
4. Place both the temp and pH sensor
tip into a satchel or cup of fresh
7.0 calibration solution. Agitate the
solution to ensure the sensor reads the
calibration solution correctly.
5. To start the 7.0 calibration, press and
hold the ENTER and UP push buttons
for 3 seconds.
