Figure 3-8. Temperature Measurement
Warning
To avoid harms to you, please do not attempt to input voltages higher than
60V DC or 30V rms AC.
To measure temperature, set up the Meter as shown in Figure 3-8 and proceed the
following.
1. Set the rotary switch to
show the room temperature.
The Meter is default to Celsius
BLUE button once you have selected the temperature function.
2. Insert the point contact temperature probe into the Meter as figure 10.
3. Place the temperature probe to the object being
measured.
The measured value shows on the display after several seconds.
Note
z Place the Meter in an environment of 18 ~23
obtained especially in testing low temperature.
z The included point contact temperature probe can only be used with temperature
230 below.
z When temperature measurement has been completed, remove the temperature
probe away from the multi-purpose socket, and remove the multi-purpose socket
away from the Meter.
4~20 mA loop current as % readout (UT71B only)
I.
It shows the mA measured value or output level in %, in a 4-20mA scale.
To use 4~20mA Loop feature, connect the Meter as follows:
1. Set the rotary switch to
feature.
2. The rest procedure, please follow B. Measuring Current: DC current measurement
(Figure 3-2).
3. When the readings obtained is:
z < 4mA, the primary display shows LO
z 4mA, the primary display shows 0%. ....
20mA, the primary display shows 100%
z > 20mA, the primary display shows HI
