RELATIVE mV MEASUREMENTS (HI 2213)

• Press

RANGE

until “

rEL

” message will be displayed on the secondary

LCD line for one second and “mV” tag will blink. After one second the
temperature will be displayed on the secondary LCD.

The reading displayed by the instrument is equal to the difference
between the current mV input value and relative mV offset established in
the relative mV calibration.

TEMPERATURE MEASUREMENTS

Connect the

HI 7662

temperature probe to the

appropriate socket and turn the instrument on.
Submerse the temperature probe into the sample and
allow the reading on the secondary LCD to stabilize.

MEMORY FUNCTION

Press and hold down

MEM

key to store the last reading

in the meters memory. The “

MEM

” tag will be

displayed.

Press

MR

(memory recall) key to display the memorized

reading. The “

MEM

” tag will be displayed.
