i) Temperature measurement
Do not get the temperature probe wet!
1. Set the function dial to
°C°F
.
2. Short press the
SEL
button to select a unit of measurement, “
°C
” or
“
°F
” will show on the display.
3. Connect the K-type thermocouple to the terminals.
- “
TEMP +
” plug to the
terminal.
- “
COM -
” plug to the
COM
terminal.
4. Measure the temperature at the probe tip.
- “OL” will appear on the display when the DMM is turned on.
- The measured temperature should be < 400 °C / 752 °F (°F = °C × 1.8 + 32)
5.
When finished measuring, disconnect the test leads and switch the power OFF.
j) Current measurement / Frequency (40 to 400 Hz)
This measuring function is suitable for measuring mains current.
To prevent possible electric shock, fire or personal injury, switch off the power supply of the circuit, and then
connect the DMM to the circuit in series before measuring the current.
If the range of the measured current is unknown, always start at the highest measurement range and switch
down to lower ranges if needed.
There are fuses inside “
10 A
” and “
mA μA
” input terminals. Do not connect the test leads to circuits in
parallel.
A warning will sound when measured values are out of range >10 A.
Measuring >5 A must only be performed for max. 30 seconds and at 15 minute intervals.
1. Set the function dial to
µA
,
mA
, or
A
, the corresponding unit of measurement will appear on the display.
2. Short press the
SEL
button to cycle through “
DC
”, “
AC
”, “
Hz
”.
3. Connect the test leads to the terminals:
- Red test lead to the
terminal.
- Black test lead to the
COM
or
10A max
terminal
4. Connect the test lead probes to the circuit in series.
5. Read the value on the display.
- DC current: The polarity is shown together with the measured value.
- AC current: Values are given in true RMS.
-
Frequency: Measuring range is 40 to 400 Hz (input amplitude ≥ range × 50 %).
6.
When finished measuring, disconnect the test leads, power the circuit down and switch the DMM power OFF
