Use steps:
1. Please unplug the electrode protective sleeve before use.
2. Clean the electrode with distilled water ,and dry it with filter paper.
3 Press the switch. Switch on the power supply.
4. Immerse the electrode into the test solution
5. Read the digital after the numerically stable.It displays temperature value below screen.
6. Press the switch after finishing reading. Wipe clean the electrode before sleeving it.
Calibration
1. Put proper 6.86, 4.00 and 9.18 standard solution apart in clean
beakers
2. In order to accurate calibration , put every buffer apart in two
beakers.One for cleaning the electrode and the other for calibration.
3. Press the switch,switch on the power supply.
4. Press "shift" button. wait until there is "6.86" digital and "---°C"
symbol. Immerse the electrode in PH 6.86 standard buffer solution
and gently shake the electrode until the display digital same as
6.86 ph of the standard solution and "----°C" display temperature.Then
complete the PH 6.86 point calibration
5. Clean the electrode with distilled water and dry it with filter
paper.Press "shift" button and repeat Step 4.
Complete the ph 4.00 point calibration
6. Clean the electrode with distilled water and dry it with filter paper. Put
the electrode into 9.18 standard solution and gently shake it until
displaying the stable digital.Display value is in the range of allowable
error.
7. This instrument calibration work is completed after all the six
steps.
Automatic temperature compensation:
The instrument with automatic temperature compensation function under measurement mode.
Maintenance
Keep the electrode clean, cover the electrode protective sleeve, please take out the batteries for long periods idle.
Low Battery Indicator
Please replace the battery if the battery symbol flashing in the upper-right corner
Warranty:
Product warranty life time from the date of purchase
The following situations are not in the range of warranty, damage caused by misemploy (battery leakage, water into circuit boards etc.) physical abuse, the label tore.
Note
1.The instrument is a professional instrument, please use under professionals instructions in order to avoid instrument failure
2. Please immerse the electrode in clear water.
Soak time: 5-10 minutes
3. Don't put the PH meter insert liquid too deep but immerse the electrode . Before use, confirm the PH electrode fixed ring is steady in order not to damage circuit board
