For short time measurement, you may power on by batteries. For long time use, you have to connect with
an AC/DC adaptor.
2. Make sure sensor probe and meter are well connected. Don't attempt to detach sensor probe from meter
while in operation.
3. When Meter shows erratic readings, it must be sensor failed or power is weak.
4. Only select one of the two electrodes while measuring the same water zone, otherwise meter appears erratic
readings. Read two parameters at the same time are only available for measuring two different water sources.
(1) POWER
NOTE: Make sure you have connected the electrode to the meter before power on.
Momentarily press PWR button to turn on the meter, press and hold PWR button to turn off meter.
(2) COND/EC/TDS/Salt MODE
Short press SET button to toggle COND → EC→ TDS → Salt
(3) CHANGE THE TEMP. UNIT TO ℃/℉
Short press UNIT button to toggle ℃ or ℉.
(4) HOLD
Freeze the current readings of Cond./EC/TDS/Salt, then icon "Hold" will appear on the top left of screen.
(5) AUTO POWER OFF
Meter will turn off automatically in 15 minutes when no use, to disable auto power off function by pressing
HOLD and PWR button, "n" momentarily shows on screen, now meter is at non-sleep mode, then turns to
normal measurement, Meter default auto power off.
(6) FACTORY RESET
a)
Cond. electrode
Whenever replacing a new cond. electrode. Long press SET+CAL to enter Cond. calibration mode then strongly
recommend doing factory reset by press SET+UNIT under 1413 uS calibration mode, screen will
show "rFS" momentarily.
(7) TEMPERATURE PROBE TYPE SELECTION
NOTE: If using NTC 10K probe but select 30K type. The temperature value will not be accurate.
Default setting is NTC 10K. User can change it depends on the electrode type to get the correct value.
NTC 10K:
Negative Temperature Coefficient 25℃ = 10 K
NTC 30K:
Negative Temperature Coefficient 25℃ = 30 K
NOT:
External temperature probe is excluded, user can enter the temperature degree by their own
temperature instrument, default: 25℃ Adjustable range: 0.0℃~90.0℃
Step 1: Must select correct probe type before measurement, otherwise the value would be incorrect.
Step 2: Long press UNIT button, the meter default is "ntc 10k", short press UNIT button to toggle ntc 30k
→ not.
Step 3: Long press UNIT button again to save the setting, meter shows "SA" at the bottom of LCD and then
return to normal measurement mode.
