The display will show the temperature.
Note: without the thermocouple in place, the display will show the ambient
temperature.
Measuring frequencies
Do not perform frequency measurements in circuits with voltages
> 250V.
Always be careful when working with voltages above 60Vdc or 30Vac rms.
Keep your fingers behind the probe barriers at all times during
measu
r
ement.
Connect the black test lead to the "COM" jack and the red test lead to the
"VHz" jack.
Select the "20KHz" range with the FUNCTION switch.
Connect the test leads to the circuit under test.
Read the measured value from the display.
Notes:
Use a shielded cable for measuring small signals in a noisy environment (min.
visible amplitude: 0.7Vpp).
