PWR: Power on (Press in one second) or power off (Press more than 2 seconds when operation).
SET: Move to left digit. Short press to toggle COND → EC → TDS → Salt. Long press to save setting.
CAL: Move to right digit. To clear SD manual record data.
MODE: Select sample rate of SD card. Toggle Cond→t1F→tds (under K value adjustment mode).
Toggle 1413 uS calibration mode to 12.8 mS calibration mode (under Conductivity calibration mode).
UNIT: Short press to change temperature unit ℃/℉. Long press to select temperature probe type.
Short press to select NTC: Negative Temperature Coefficient)/ NOT: no remote temperature probe.
HOLD: Freeze current readings (Hold shows at top of LCD). Increase value.
ADJ: Long press to start SD recording (SD card is inserted to the meter). Decrease value.
SET+UNIT: Enter cond. cell constant K value / Temp. coefficient compensation/tds K factor value mode.
Long press again to escape the K value setting. Recovery to factory setting (under calibration mode).
SET+CAL: Conductivity Calibration.
HOLD+PWR: Disable Auto Power Off.
OPERATION
COND/EC/TDS/SALT PROBE INSTALLATION (BNC connector):
a)
Insert the COND electrode into the top of left hole. And insert the 3.5mm Ø diameter phone jack ATC
sensoring 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 anymore.
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：remove
batteries when not use！)
1. There are two ways to provide power:
(a) AAA batteries x 3pcs
(b) 9V AC/DC adaptor.

Battery life: Approx. 50 hours for continuous used. Approx. 11.5 hours for activating SD function (w/
sample rate: 2 seconds). Approx. 13 hours for activating SD function (w/ sample rate: 1 hrs).
