MEASURING SCALE - °C/°F (HI 9040 only)
The meter automatically defaults to the °C
scale when turned on. Measurements can be
performed in either the Centigrade or Fahren-
heit scale. To change the scale, press the
"°C/°F" button once.
HOLD MODE (except for HI 9041)
The hold function is activated by either the
HOLD (HI 9040) or HOLD/MEM (HI 9050
and HI 9051) key. The measured tempera-
ture is frozen on the display when this key is
pressed. A blinking "M" on display indicates
the operational mode. By pressing the key
one more time, the meter returns to measure-
ment mode.
HI/LO FUNCTION (except for HI 9041)
The maximum and minimum temperatures
are continuously monitored. The contents may
be recalled and/or cleared at any time during
measurement.
Enquires of the highest or lowest temperature
measured may be made by pressing and hold-
ing down the respective HI or LO key. The
appropriate display indicator, "HI" or "LO",
will light up together with the value retrieved
from memory. Release the key to resume
normal operation.
CLEAR FUNCTION (except for HI 9041)
Upon pressing the CLEAR key, the memory is
cleared and the present measurement read-
ing is assigned to the highest and lowest
temperature memories, i.e. the temperature
reading is equal for both memories. The "HI"
and "LO" display indicators will blink twice to
alert the user.
