OPERATION
pH INSTALLATION (BNC connector):
a)
Insert the pH electrode into the top of right hole. And insert the 3.5mm Ø diameter phone jack ATC sensor
parts into the middle of hole.
b)
Hold the BNC connector in one hand; with the other, insert the braid into the center of the connector.
Continuing pushing the braid into the connector until it will not go in any farther. Do this gently and slowly;
do not bend the braid.
c)
Turn the BNC connector in a clockwise direction, until you cannot turn it any more.

detecting the buttons per milliseconds, letting meter know if the user wants to activate the meter or not. It will
consume the power by each detecting, in order to save the power, you may pull down the switch.
NOTE:
For each operation, make sure you are using fresh batteries, same brand, same power of batteries is
required, and
otherwise meter shows erratic readings or leakage. Warranty is void if not follow the notices. (Note
：

1. Power supply:
(a) AAA batteries x 3pcs.
(b) Battery icon
indicates when power is weak, replace with new batteries immediately as the readings
now on
LCD are incorrect due to weak power.
Battery life: Approx. 50 hours for continuous used.
2. Make sure sensor electrode
and meter are well connected. Don’t attempt to detach sensor probe from meter
while in operation.
