2-3. Safety Warnings
2-3-1. To prevent electric shock hazard and/or damage to the meter,
do not measure voltage exceeding 1000V DC or 750V AC.
2-3-2. To avoid damage to the meter and/or injury, observe the input
limits as stated in Table 1.
2-3-3. To avoid damage to the meter, disconnect test leads from test
points before changing the function/range.
2-3-4. To avoid electric shock, use caution when working above 60V
DC or 25V AC RMS. Such voltage pose a shock hazard.
2-3-5. The 20A range is protected by the fuse. To avoid damage or
injury, use the meter only in circuits limits by fuse or
circuit-breaker to 20A or 4000VA.
Do not apply voltage to between 20A or mA and COM
terminals. This warning is to assure protection against injury
and/or damage to the meter and the user.
2-3-6. Do not get the meter and test leads wet.
2-3-7. Ensure the test leads are in good condition.
