disappear and the correct temperature reading will be
displayed. It is not necessary to press the [CLEAR] key.
mV MEASUREMENTS
1. Measurement in the mV-AUTOLOCK mode.
1.1 Connect the optional combination ORP electrode to the
BNC connector of instrument.
1.2 Press the [MODE] key for the LCD to indicate mV and
for the AUTO annunciator to be on.
1.3 Rinse the electrode with distilled water and immerse
it in the sample to be measured.
1.4 Press the [MEA./EFF.] key. The WAIT annunciator will
start to flash. This means the instrument is waiting
for a stable reading. The display will track the mV
value as sensed by the electrode,. When the display
changes less than 1 mV within 10 seconds, the AUTOLOCK
function will be activated. The WAIT annunciator will
stop flashing and stay off. The reading is then locked
and will not respond to further changes from the
electrode. The “lock” display is the mV value of the
sample.
If "OvEr/Undr" is displayed, the mV value measured is
out of the “-2000/+2000 mV” range. The instrument
will display the correct value once the input mV is
brought within range. It is not necessary to press the
[CLEAR].
1.5 The ATC/Temp probe can be used to measure the sample
temperature as required.
