Temperature Measurements
The model pH100A can measure temperature independently with the ATC/Temp probe
without using the pH electrode. Place the ATC/Temp probe in the media to be measured.
The measured temperature displays.
mV Measurements
1. Connect the optional combination mV electrode to the unit. Press MODE to enter mV
mode with AUTOLOCK on or off as desired. For inherently unstable samples, the unit will
not AUTOLOCK. Use mV mode with AUTOLOCK off in this case.
2. Rinse electrode with distilled water and immerse it in sample to be measured. If
AUTOLOCK is off, the mV value of the sample will be displayed on the screen. If
AUTOLOCK is on, press MEA./EFF. “WAIT” flashes until the unit determines a stable mV
reading.
Saving, Viewing and Deleting Data
The pH100A can save 50 data records. When in measurement mode, press ESC to save a
record. The instrument will confirm the saved data by displaying SAVE and the record
number for one second. “Full” is displayed when trying to save data and the memory is full.
To view saved data, press mode until RECALL is displayed and then press ESC. Use the Up
or Down arrow keys to review different saved records. Press Mode to escape back to
measurement mode.
To delete data records, press Mode while in measurement mode until DELETE is displayed.
Press ESC . “All” will be displayed and blinking. Press the Up or Down arrow key to switch
between delete ‘All’ or ‘Each’ options. Select either ‘All’ or ‘Each’ by pressing ESC while that
option is displayed.
If ‘All’ is selected, all records will be deleted from memory and ‘None’ will be displayed. Press
Mode twice to return to the measurement mode.
If ‘Each’ is selected, the Up and Down arrow keys will allow you to scroll through the saved
data records. Press ESC to delete the selected record. All records after the deleted
record will shift up to keep the records in sequential order. For example, if record 3 is
deleted, record 4 will become record 3 and record 5 will become record 4. Press Mode twice
to return to the measurement mode.
