CAUTIONS
 Improper use of this meter can cause damage, shock, injury or death. Read and understand this user
manual before operating the meter.
 Always remove the test leads before replacing the battery or fuses.
 Inspect the condition of the test leads and the meter itself for any damage before operating the meter.
 Use great care when making measurements if the voltages are greater than 30VAC rms or 60VDC. 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.
 This device is not a toy and must not reach children's hands. It contains hazardous objects as well as small
parts that the children could swallow.
 In case the device is going to be unused for an extended period of time, remove the batteries and store
them separately.
 Expired or damaged batteries can cause cauterization on contact with the skin. Use protective gloves
when handling.
 Do not short‐circuit the batteries. Do not throw batteries into a fire.
This meter has been designed for safe use, but must be operated with caution. The rules listed below must
be carefully followed for safe operation.
1. NEVER apply voltage or current to the meter that exceeds the specified maximum:
Function
V DC or V AC
µA/mA AC/DC
A AC/DC
Frequency, Resistance, Capacitance, Duty Cycle,
Diode Test, Continuity
2. USE EXTREME CAUTION when working with high voltages.
3. DO NOT measure voltage if the voltage on the "COM" input jack exceeds 600V above earth ground.
4. NEVER connect the meter leads across a voltage source while the function switch is in the current,
resistance, or diode mode. Doing so can damage the meter.
5. ALWAYS discharge filter capacitors in power supplies and disconnect the power when making resistance
or diode tests.
6. ALWAYS turn off the power and disconnect the test leads before opening the covers to replace the fuse
or batteries.
7. NEVER operate the meter unless the back cover and the battery and fuse covers are in place and fastened
securely.
8. NEVER change the measurement function by turning the function dial while testing.
9. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
