This symbol adjacent to another symbol, terminal or
operating device indicates that the operator must refer to an
explanation in the Operating Instructions to avoid personal
injury or damage to the meter.
This WARNING symbol indicates a potentially hazardous
situation, which if not avoided, could result in death or
serious injury.
This symbol indicates that a device is protected throughout
by double insulation or reinforced insulation.
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:
Input Protection Limits
Function Maximum Input
V DC or V AC 600V DC/AC
µA AC/DC 200mA 500V fast acting resettable fuse
Resistance, Diode Test,
Continuity Test
600V DC/AC
2. USE EXTREME CAUTION when working with voltages greater than 25VAC
or 35VDC. These voltages are considered a shock hazard.
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, continuity or diode tests.
6. ALWAYS turn off the power and disconnect the test leads from the circuit
before opening the cover to replace the batteries.
7. NEVER operate the meter unless the battery cover is in place and fastened
securely.
