2. PRODUCT SPECIFIC SAFETY INFORMATION
Measurement Category III (CAT III) is applicable to test and
measuring equipment connected to the distribution part of the
building's low-voltage MAINS installation.
Measurement Category IV (CAT IV) is applicable to test and
measuring equipment connected at the source of the building's low-
voltage MAINS installation.
2.1 Precautions
This product has been designed with your safety in mind, but
please pay attention to the following warnings and cautions before
use.
Warning
Before use check the unit for cracks or any other damage. Make
sure the unit is free from dust, grease and moisture. Also check any
associated leads and accessories for damage. Do not use if
damaged.
Warning
Do not use if the battery/fuse cover is not fitted.
Warning
When this unit is used in combination with test leads, the
measurement category of the combination is the lower
measurement category of either this unit or the test leads used.
Likewise, if test lead accessories such as crocodile clips are also
used, the measurement category will be the lowest measurement
category in that combination.
3. OPERATION
3.1 General
If the multimeter does not measure current the internal fuse (F1)
may have blown (see section 4.2 Fuse Replacement).
If the multimeter does not measure capacitance the internal fuse
(F2) may have blown (see section 4.2 Fuse Replacement).
If the magnitude of a parameter to be measured is unknown, but
known to be within the maximum safe limits of the multimeter, then
manually set the range to maximum. For example, if measuring DC
voltage and the voltage magnitude is unknown, set the range to
600V, then if required reduce the range for a satisfactory reading.
If the multimeter displays OL or -OL then the measurement limits
of the range have been exceeded.
3.2 Low Battery Indication
If the
symbol is displayed then the battery needs replacing
(see section 4.1 Battery Replacement).
3.3 Description of Terminals
F
Input terminal for capacitance measurements
mA
Input terminal for AC & DC current measurements
COM
Common terminal for all measurements
VΩ
Input terminal for AC & DC voltage, resistance
continuity, diode and frequency measurements
TYPE K

3.4 Description of Press Buttons
MAX/MIN Selects maximum/minimum function
Turns on/off the backlight
Warning
Always test this unit on an appropriate proving device or known
voltage source before and after using it to determine if a
hazardous voltage exists in a circuit to be tested.
Warning
When using test leads, always keep your fingers behind the finger
guard on the test lead probe.
Warning
Measuring a voltage that exceeds the specified limits of the unit
may damage the unit and expose the operator to a shock hazard.
Always check the unit's specified limits before use.
Warning
To avoid electrical shock, and damage to the instrument, do not
use this instrument and the associated temperature probe when
voltages at the measurement surface exceed 30V AC rms or 60V
DC.
Caution
To avoid burns or damage to equipment, do not take temperature
measurements inside microwave ovens.
Caution
Avoid severe mechanical shock or vibration and extreme
temperature.

Indicates battery is low
3.6 Max/Min
To select the Max/Min function press the Max/Min button.
Alternate between displaying the maximum and minimum
measured values by pressing the Max/Min button.
To exit the Max/Min function hold down the Max/Min button for 2
seconds.
3.7 Backlight
Press the
button to turn on/off the backlight.
The backlight will automatically turn off after approx 4½ minutes.
3.8 Voltage Measurement
Connect the black test lead to the COM terminal and the red test
lead to the VΩ terminal.
Set the rotary switch to either AC V or DC V and the required
range.
Taking all necessary safety precautions connect the test leads to
the circuit being measured and read the measured voltage from
the display.
3.9 Current Measurement
Connect the black test lead to the COM terminal and the red test
