SAFETY INFORMATION
WARNING
Take care when using this meter. Improper use can result in electric shock or
damage to the meter. Take all normal safety precautions and follow the
safeguards suggested in this manual.
PRELIMINARY
1. When using the meter, the user must observe all normal safety rules
concerning:
General protection against electric shock
Protection of the meter against misuse.
2. When the meter is delivered confirm it has not been damaged in
transit.
3. The test leads must be kept in good condition. Before using, check
that the insulation on the test leads has not been damaged or any wire
exposed.
4. Use only the test leads supplied to ensure operational safety. If
necessary, they must be replaced with test leads of the same model or
class.
DURING USE
1. Do not take measurements that exceed the maximum values for this
meter.
2. Do not touch the metal probes of the test leads when the meter is
connected to the circuit being measured.
3. Keep your fingers behind the probe barriers when taking
measurements.
4. Do not take voltage measurements if you suspect the value exceeds
600V.
5. If the appropriate value range is unknown, select the highest rangeon
the scale.
6. Disconnect the test leads from the circuit under test before turning the
rotary function selector.
7. Do not measure the resistance, diode or continuity of live circuits.
8. Do not connect the meter to any voltage source while the rotary
selector is in the Current, Resistance, Diode or Continuity range.
5
9. Do not use the meter near explosive gases or steam.
10. Stop using the meter if any abnormalities or faults are observed.
11. Do not use the meter unless its rear case and battery cover is correctly
and securely fastened.
12. Do not store or use the meter in areas exposed to direct sunlight, at
high temperature or with high relative humidity.
13. To avoid false readings, replace the batteries as soon as the Low
Battery indicator appears.
14. Before use, verify the meter operation by measuring a known voltage.
15. Never touch exposed wiring, connections or any live circuit while
taking any measurements.
16. Keep your body isolated from ground by using dry clothing, rubber
shoes, rubber mats or any approved insulating material.
SYMBOLS

OPERATION INSTRUCTIONS
1. Switch on the power by turning the rotary selector. If the battery
voltage is low, the symbol will appear and the batteries should
be replaced.
2. Turn the rotary selector to the required function to be measured.
Choose the highest range when the value to be measured is unknown.
3. Connect the earth test lead before the positive test lead when
making the connection. Remove the positive test lead first when
disconnecting.
SELECTING RANGES
When the meter is turned on, it will be in the Auto Range mode for
measuring current, voltage, resistance and continuity.
1. Press the RAN button for Manual Range mode. The range will go up
one level at each press and return to the lowest level when the highest
level is reached.
2. Press the RAN button, for two or more seconds to return to the Auto
Range.
3. Press the RAN button when measuring the maximum or minimum
value, and the meter will return to the normal working condition.
SELECTING FUNCTIONS
1. Press the SEL button to switch between AC and DC voltage
measurement ranges.
2. Press the SEL button to switch between diode and continuity
measuring ranges.
HOLDING READINGS
1. Press the HOLD button to hold the readings while taking
measurements.
• The value on the display will be held.
2. Press the HOLD button again to release the function.
SELECTING MAXIMUM VALUE
1. Press the MAX button to show the maximum value measured.
2. Press the MAX button again to return to standard mode.
