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.
