2. Safety
2-1.International Safety Symbols
This symbol, adjacent to another symbol or terminal, indicates the user must
refer to the manual for further information.
This symbol, adjacent to a terminal, indicates that, under normal use,
hazardous voltages may be present.
Double insulation.
Application around and removal from uninsulated hazardous live conductors
is permitted.
2-2.Safety Notes
• Do not exceed the maximum allowable input range of any function.
• Do not apply voltage to meter when resistance function is selected.
• Set the function switch OFF when the meter is not in use.
• Remove the battery if meter is to be stored for longer than 60 days.
2- 3.WARNINGS
• Set function switch to the appropriate position before measuring.
• When measuring volts do not switch to current/resistance modes.
• Do not measure current on a circuit whose voltage exceeds 1000V.
• When changing ranges always disconnect the test leads from the circuit under
test.
• Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user's authority to operate the
equipment.

2- 4.CAUTIONS
• Read and understand this user manual before operating the meter.
• Improper use of this meter can cause damage, shock, injury or death.
• Always remove the test leads before replacing the battery .
• If the test leads need to be replaced, you must use a new one which should
meet EN 61010-031 standard.
• Inspect the condition of the test leads and the meter itself for any damage
before operating the meter, repair or replace any damage before use.
• Use great care when making measurements if the voltages are greater than
25VAC rms or 35VDC, these voltages are considered a shock hazard.
• Always discharge capacitors and remove power from the device under test
before performing Diode, Resistance or Continuity tests.
• Voltage checks on electrical outlets can be difficult and misleading because
of the uncertainty of connection to the recessed electrical contacts, other
means should be used to ensure that the terminals are not “live”.
• If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

the same key is pressed again.
3. The display shows the symbol associated with the selected function: “PMAX”
for maximum peak value, “PMIN” for minimum peak value.
• Inrush Function
Note: Only ACA functions can do the INRUSH value measurement.
1.Close motor and then install Jaw.
2. Press the Peak/Inrush/ESC Button, “ --- ”will appear in the display.
3. Open motor and then read the value on the display.
• ESC it goes back to a normal measuring mode.
