4. If the pair is not successful, do steps
again.
Note: If there is more than one meter in range, each meter is identified with the model number and the serial
number (e.g., H170G LP SN1 2755).
Send data to a PC
Transmit data in storage to a PC and see real-time measurement values from a remote location on a
PC. Refer to the SmartLogger II PC software guide for operation instructions for the PC to USB
connection.
1. Set the power to off.
2. Connect the USB cable to the USB port of the PC.
3. Use the USB drivers to make a USB connection to the PC.
4. Set the power to on. Refer to the SmartLogger II documentation for data transfer information.
Maintenance
Replace the batteries
The display shows "bAt" when the batteries are too low to give a reliable measurement. The low
battery icon (refer to
on page 13) shows when there is approximately 25 hours of
battery power. Measurement errors are possible when the batteries are low. Refer to
on page 10 to replace the batteries.
Note: The date and time must be set again when the batteries are removed or are fully discharged.
Clean the instrument
Clean the exterior of the instrument with a moist cloth and a mild soap solution and then wipe the
instrument dry.
ISFET pH probe maintenance
C A U T I O N
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
C A U T I O N
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
The expected life of an ISFET probe is approximately 18 months. The reference electrode has a KCI
gel that is diluted over time. The reference is sealed and is non-refillable. Replace the probe when it
becomes difficult to calibrate.
• Keep the probe dry with the protective shroud on when not in use.
• Clean oil, fat, food particles, starch, protein or other materials from the probe tip after use.
• Never use sharp metal objects (e.g., a needle, a pin, etc.) to clean the sensor surface.
• Remove the probe from environments with static electricity. Electrostatic discharge (ESD) can
permanently damage the probe.
• Remove the probe from environments that will damage the sensor, such as hydrofluoric acid or
abrasive samples.
