• 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
measurement.
• Connect the black test lead to the "COM" jack and the red test lead to the
"VΩHz" 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).
