Instruction Manual PCD 650

2.2.5 Automatic Temperature Compensation (ATC)

Connect an appropriate probe with built in ATC probe to the meter and select

‘ATC mode’ in the temperature setup (See page 98) for the

pH/conductivity/DO reading to be automatically compensated for temperature

variations.

If you select ‘ATC’ without connecting a probe to the meter, the LCD shows

‘UNDER’ for temperature reading.

Figure 18: Under range

NOTE: The factory default value for normalization temperature is 25 °C.

2.2.6 Manual Temperature Compensation (MTC)

If ATC probe is not available, you can choose to manually compensate for

temperature. This is suitable when the temperature of your sample is

sufficiently stable. Select ‘MTC mode’ in the temperature setup (see page 98).

Press CAL (F2) and then press NEXT key. Press TEMP (F1) to go to

temperature calibration. Enter the temperature value of your sample. See

page 45 for more details on temperature calibration.

2.2.7 Alarm set point (For pH/conductivity/DO)

You can set the meter to display an alarm when the

pH/conductivity/salinity/resistivity/TDS/DO(%)/DO(mg/L) reading goes higher

or lower than predefined set points. Refer Setup of respective modes to set

alarm points for pH, conductivity and DO.

2.2.8 Calibration Due (CAL-DUE) Indicator (For pH/conductivity/DO)

You can set a reminder to be displayed in the LCD when the next calibration

is due. Set the number of days in the pH/conductivity/DO Setup and the

meter will remind you when the days elapse from your last calibration date.

2.2.9 Resolution of pH Reading

By default, the resolution is set to 0.00. You can change the resolution in the

setup mode. pH resolution can be adjusted from 0.1 to 0.001 pH (See page

83)

2.2.10 pH buffer group for calibration and auto-recognition

This option allows you to choose buffer group from four internationally

recognized standard buffer groups namely USA, NIST, DIN & PWB. The

default buffer group is USA. Refer ‘pH Setup’ section in page 82 for

information on how to set the meter to a particular buffer group.
