measured.
1.4 Press the MEASURE key. The WAIT annunciator will flash until the unit
determines a stable mV reading. When WAIT stops flashing and stays off,
the reading is locked.
1.5 The ATC/Temp probe can be used to measure the sample temperature as
required.
1.6 For inherently unstable samples, the unit will not AUTOLOCK. Use the
mV mode with AUTOLOCK off in the case.
2. Measurement in the mV mode.
2.1 Connect the optional combination ORP electrode to the unit.
2.2 Press the MODE key repeatedly until the unit display mV mode.
2.3 Rinse the electrode with distilled water and immerse it in the sample to be
measured.
2.4 Allow sufficient time for the display to stabilize. The unit will display the
mV value of the sample.
2.5 The ATC/Temp probe can be used to measure the sample temperature as
required.
SAVING, RECALLING AND ERASING DATA (
See Notes 2 and 3
)
1. Saving readings to memory.
1.1 While in pH-AUTOLOCK, mV-AUTOLOCK, pH and mV modes, press
and hold the MEASURE key for about 2 seconds. The unit will display
“SAV” and the site number for a brief moment to indicate a successful
saving.
1.2 If it displays “FUL”, this means that all 40 sites are used up. You should
export data from the unit as soon as possible. Any subsequent saving of
data will overwrite the existing data.
2.
Recalling readings from memory.
2.1 To recall the data, press the MODE key repeatedly until the unit displays
RECALL mode.The“℃” annunciator flashes until the unit exit the
RECALL mode.
2.2 Press
∆or∇ keys to adjust / select the site number.
2.3 Press the MEASURE key to display the data that has been saved on the
selected site number. The unit will display pH and temperature, and press the
MEASURE key again to display mV and temperature. By pressing the
MEASURE key, the meter will display these two sets of stored values
alternately.
3. Erasing
data.
