Hach-Lange MTC10130 - Manual (Page 9)

Change measurement options
Methods are groups of default or user-defined settings relevant to specific applications. If
the meter is set to the default method and the Modify Current Settings option is chosen, a
prompt for a new name is shown after the changes are entered. The settings are saved
with this name to distinguish them from the default method settings, which cannot be
changed. A saved method can be used instead of multiple adjustments to the individual
settings. Changes made to a user defined method are automatically saved with the
existing name. Multiple methods can be saved for the same probe on each meter.
1. Make sure a probe is connected to the meter.
2. Push and select MTC101 Settings.
3. Select Modify Current Settings.
4. Select Measurement Options and update the settings:
Option Description
Response Time Sets the response time—
• Fast (2 mV/minute)
• Medium (1 mV/minute) (default)
• Slow (0.5 mV/minute)
The response time affects the speed of the measurement by adjusting the
stabilization criteria.
Measurement
Limits Sets the measurement limits—Lower limit (default: -1200.0 mV) or Upper
limit (default: 1200.0 mV).
The measurement limits can be set to match the acceptable values for
the sample. When the measurement is above the upper limit setting or
below the lower limit setting, the meter shows an "Out of limits" message.
This message is an alert to a potential problem with the process
conditions.
5. If prompted, enter a name for the new method settings. Additional changes made to
the settings of an existing method are automatically saved with the same method
name.
6. Push EXIT until the meter returns to the measurement mode.
Change calibration options
1. Make sure a probe is connected to the meter.
2. Push and select MTC101 Settings.
3. Select Modify Current Settings.
4. Select Calibration Options and update the settings:
Option Description
Standard Sets the calibration standard—
• ZoBell’s (221mV – 25 °C)
• Light’s (468mV – 25 °C)
• Custom
Temperature compensated for ZoBell’s solution.
Standard values are shown on the Calibration Options screen.
Light’s solution is characterized at 25 °C.
Custom standard values and temperature are user-defined.
