Measuring Temperature; 4~20Ma Loop Current As % Readout - Egatronic 51253 Manual De Instrucciones

2. Set the rotary switch to
select the Hz measurement mode for frequency measurement or % for duty cycle measurement.
The BLUE button cycles among
3. Connect the test leads across with the object being measured.
The measured value shows on the primary display.
Note
The requirement of Input amplitude "a" is as follows:
When 10Hz~40MHz: 200 mV a 30Vrms;
>40MHz: Un-specified
When Hz measurement has been completed, disconnect the connection between the testing
leads and the circuit under test and remove the test leads away from the input terminals.
H. Measuring Temperature (COD. 51254 only)
Warning!
To measure temperature, set up the Meter as shown in Figure 3-8 and proceed the following.
Set the rotary switch to ºC ºF, the display shows OL. Short circuit the test leads to show the room
temperature. The Meter is default to Celsius ºC degree unit, you can change units by press the
BLUE button once you have selected the temperature function.
1. Insert the point contact temperature probe into the Meter as figure 10.
2. Place the temperature probe to the object being measured.
3. The measured value shows on the display after several seconds.
