2.4 Restoring Factory Calibration

The TN-100/ T-100 turbidimeter allows you to reset the meter back to the

factory default calibration values. This feature is extremely useful when

there are errors in calibration or when you have new calibration standards.

1. With the meter switched off, press ▲ and ON/OFF keys simultaneously

for about 2 seconds.

2. The display will flash [URST] (User-Reset) for 2 seconds and show

[No], which is the default value.

3. Use ▲ or ▼ key to select between [YES] or [No].

 [YES] = To restore meter back to factory calibration values

 [No] = To retain last calibrated values

4. After selecting [YES] or [No], press READ/ENTER key.

5. The display will flash [--Rd--] 10 times.

6. Once it stops flashing, it will show [--Rd--]. It is now ready to take

turbidity measurements.

Figure 5 shows the sequence for restoring factory calibration values.
