4. Configuration

4.1 Illustration of front panel of PC-310A

1.

:

Power switch key. RELAY and analog output are not working under OFF status;

while, RELAY and analog output are working under ON status.

2.

:

Calibration key. After pressing it to enter calibration mode, RELAY function is not

working even though the reading is fluctuating and also analog output signal will

remain as what it was before HOLD status. Then, it will show current measuring

values, STDBY sign and pH or mV sign will be twinkling. Move on calibration by

adjusting CALIB knob and SLOPE knob and then press STDBY once finished.

After that, STDBY sign will disappear and pH or mV sign will cease twinkling, which

means calibration is complete and calibration data is stored. Finally, it will go back to

measurement mode and both RELAY & analog output resume working.

Note 1:

After calibration is complete, it is necessary to press knob to confirm that

calibration data has been stored; however, it has not without pressing it and it will go

back to measurement mode in 20 minutes automatically and a new measurement will

follow previous calibration data.

Note 2:

If a sign “----“ on top of display and measuring value are shown in turn, it suggests that

CALIB knob has reached a mechanical boundary; nevertheless, if a sign “----“ on

bottom of display and measuring value are shown in turn, it suggests that SLOPE knob

has reached a mechanical boundary. If it shows " " on display, it suggests that

both CALIB and SLOPE have reached their mechanical boundary. It is available for

user to turn the knob in a reverse way if abovementioned conditions occur. If it still

fails to reach a desired calibration value, it means that a shift to zero-point potential or

slope is way much. It is recommended to use new pH standard buffers or conduct

maintenance for pH electrodes. Replace the pH electrode if above two methods fail.

3.

CALIB knob:

pH7.00 adjustment knob; ORP adjustment knob

Note: When STDBY sign or pH sign is twinkling, it is valid to turn CALIB knob. It is invalid

besides that in case that measuring values may be adjusted at random.
