If you need to measure duty cycle, press Hz% button to select % measurement.
Note:
• Input amplitude: When 10Hz~10MHz: 300mV < a < 30Vrms
H. Temperature measurement (see fi gure 9)
The included K type point contact temperature probe can only be used in the measurement
below 230°C. To avoid harm yourself, do not input voltages higher than DC 60V or AC
30Vrms.
To measure temperature, connect the meter as follows:
1. Set the rotary switch to °C °F
2. Insert the temperature probe into the input terminal as shown on fi gure 9
3. Place the temperature probe to the object being measured. After a few seconds, the
measured value shows on the display.
4. Press BLUE button to switch between °C and °F temperature.
Note:
• To avoid measurement error, especially for low temperature measurement, the operat-
ing temperature should not exceed 18°C ~28°C.

symbol on the LCD display will disappear.
• If the meter is carrying out HOLD, MAX/MIN or REL measurement, the LCD will display
the corresponding readings, but the interface output will still be the random value of
the present input terminals measurement.
