Warning!
1. SAFETY
1.1. PERSONAL PRECAUTIONS
9 When using this meter, please observe all normal safety rules concerning:
Protection against the dangers of electric current.
Protection of the meter against misuse.
9 Full compliance with safety standards can only be guaranteed if used with the test leads supplied. If necessary, they must be replaced
with genuine Sealey leads with the same electronic ratings. Failure to do so will invalidate the warranty.
8 DO NOT use leads if damaged or if the wire is bared in any way.
1.2. GENERAL SAFETY INSTRUCTIONS
9 Familiarise yourself with the applications, limitations and hazards of the meter. IF IN ANY DOUBT CONSULT A QUALIFIED
ELECTRICIAN
9 When the meter is linked to a measurement circuit, do not touch unused meter terminals.
9 When the scale of the value to be measured is unknown set the selector to the highest range available.
9 Before rotating the rotary switch to change functions, disconnect test leads from the circuit under test.
WARNING! Never perform resistance measurements on live circuits.
9 Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe guards while measuring.
9 When not in use, store the meter carefully in a safe, dry, childproof location. Storage temperature range -10°C to 50°C.
8 never apply voltage or current to the meter that exceeds the specified maximum.
9 The user shall ensure that test probes are correctly selected in order to prevent danger. Probes shall be selected to ensure that
adequate barriers guard against inadvertent hand contact with live conductors under test and that probes have minimal
exposed probe tips. Where there is a risk of the probe tip short circuiting with other live conductors under test, it is recommended
that the exposed tip length shall not exceed 4mm.
9 The warnings, cautions and instructions referred to in this manual cannot cover all possible conditions and situations that may occur.
It must be understood that common sense and caution are factors which cannot be built into this product, but must be applied by the
operator.

4. OPERATION
WARNING! ensure that you read, understand and apply the safety and operational instructions before connecting the meter. 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 on meter before use and to turn it off when measurement is completed.
Note: IF “ol” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher rating.
Note: on some low AC and dC ranges, with the test leads not connected to a device, the reading may show a random fluctuating reading.
This is normal and is caused by the high input sensitivity. The reading will stabilise and give a proper measurement when connected to a
circuit.
4.1. ModeButton(g.1.11)
4.1.1. To select AC/dC voltages, AC/dC current, Resistance, diode, Continuity and Capacitance check.
4.2. RangeButton(g.1.7.)
Note: When the meter is first turned on, it automatically selects the best range for the measurements being made and is generally the best
setting for most measurements. For measurements situations requiring that a range be manually selected, perform the following.
4.2.1. Press the Range button. The “AUTo” display indicator will turn off.
4.2.2. Press the range button to step through the available ranges until you select the range you want.

4.3.5. The backlight will automatically turn off after approx 10 seconds.
4.4. Relative Button (fig.1.8.)
4.4.1. The relative measurement feature allows you to make measurements relative to a stored reference value. A reference voltage, current etc
can be stored and measurements made in comparison to that value. The displayed value is the difference between the reference value
and the measured value.
4.4.2. Perform any measurement as described in the operating instructions.
4.4.3. Press the relative button to store the reading in the display and the “Rel” indicator will appear in the display.
4.4.4. The display will now indicate the difference between the stored value and the measured value.
4.4.5. Press the relative button to return to normal operation.
4.5. Hz/% Duty Button (fig.1.6.)

4.7.3. Press the mode button to select AC or dC current.
4.7.4. Touch the test probes in series with the circuit under test and read the current on the display.
4.8. Resistance, Diode, Continuity or Capacitance Measurements
WARNING! To avoid electric shock, disconnect power to unit under test and discharge all capacitors before taking any
resistance or capacitance measurements.
4.8.1. Insert the black test lead into the negative “COM” jack and the red test lead into the positive Ω CAP jack.
4.8.2. Turn the rotary switch to the Ω CAP position.
4.8.3. Press the Mode button (fig. 1.11.) to select Ω or or or CAP.
4.8.4. Connect the test probes to the two ends of the Resistance, diode, Continuity, Capacitance or circuit to be measured.

4.8.7. When measuring the forward voltage across a good diode 0.4V or 0.7V will be indicated and the reverse voltage will indicate “ol” (same
as on open condition). For a short circuit diode, a value of 0mV will be displayed.
WARNING! When checking in-circuit capacitance, be sure to disconnect the power supply from the circuit and that the
capacitors are fully
4.9. Frequency or Duty Cycle measurements
discharged. The range control mode in capacitance measurement is auto-ranging.
4.9.1. Insert the black test lead into the negative “CoM” jack and the red test lead into the positive “Hz” jack.
4.9.2. Turn the rotary switch to the “Hz %dUTY” position.
