9. MEASURING OPERATIONS
To perform a measuring operation connect the sensor at socket M (see Chap-
ter 7). The measured value is acquired continuously at 2.5 mops.
9.1 Measured value
After switching ON first of all a segment test is
performed; then the battery voltage appears and
if the batteries are almost empty (< 3.8 V) the
LO-
BAT
arrow also appears.
(see Section 6.1)
The battery voltage display can be repeated at
any time by pressing key
ON
.
In the main field you will then see the tempera-
ture value with its units; in the function field you
will see the abbreviation for the thermocouple
(see Section 10.1). All special operating states
possible for the measured value are explained in
Section 8.1.
9.2 Measured value functions
By pressing key
M▲
units °C and °F can be selected one after the other and
as a check also the voltage in mV or the internal cold junction temperature, if
these functions have been enabled (see Section 10.3). The current measured
value is displayed in the main field together with the appropriate units. By
pressing key
M▼
you can jump back to the previous function.
To select the measured value function press keys :
