4. OPERATION
WARNING! Ensure that you read, understand and apply the safety and operational instructions before connecting the analyser. Only when you are sure
that you understand the procedures is it safe to proceed with testing.
WARNING! risk of electrocution. High voltage circuits, both AC and DC are very dangerous and should be measured with great care.
Operating temperature range 0°C to 40°C.
Remember to turn off analyser when measurement is completed.
Note:
If "OL" appears in the display during a measurement, the value exceeds the range you have selected. Select a higher range.
Note:
On some low AC and DC ranges, with the test leads not connected to a device, the display may show a random fluctuating reading. this is
normal and is caused by the high input sensitivity. the reading will stabilise and give a correct measurement when connected to a circuit.
4.1.
Data Hold Button
4.1.1.
the data hold function allows the analyser to freeze a measurement reading for later reference.
4.1.2.
Press the data hold button once to freeze the reading in the display. the indicator "H" will appear in the display.
4.1.3.
Press the data hold button again to return to normal operation.
4.2.
AC/DC voltage measurement
4.2.1.
Insert the black test lead into the negative COm socket and the red test lead into the positive
4.2.2.
turn the function dial to the voltage setting and press the function selection button to select AC or DC as required.
4.2.3.
Connect the test leads to the circuit under test and read the voltage on the display.
4.2.4.
For DC voltage, the polarity of the red test lead will be displayed as well as the value.
4.3.
DC Current measurement
WARNING! Do not make current measurements at 10A for longer than 10 seconds in every 15 minutes. Exceeding this may cause damage to
the analyser and test leads.
4.3.1.
Insert the black test lead into the negative COm socket, and the red test lead into the positive µAmA socket (or the positive 10A socket for currents from
326mA to 10A).
4.3.2.
turn the function dial to the appropriate setting as required (see ranges above). If the current range to be measured is not known, set to the highest
range setting, and then select to the correct range when the first reading is taken, until satisfactory resolution is obtained. Press the function selection
button to select AC or DC as required.
4.3.3.
Connect the test leads in series with the circuit under test and read the current on the display.
4.3.4.
For DC current, the polarity of the red test lead will be displayed as well as the value.
