1. SAFETY INFORMATION

The following safety information must be observed to insure maximum

personal safety during the operation at this meter:

Ÿ Do not use the meter if the meter or test leads look damaged, or if you

suspect that the meter is not operating properly.

Ÿ Never earth yourself when taking electrical measurements. Do not

touch exposed metal pipes, outlets, fixtures, etc., which might be at

earth potential. Keep your body isolated from earth by using dry

clothing, rubber shoes, rubber mats, or any approved insulating

material.

Ÿ Turn off power to the circuit under test before cutting, unsoldering, or

breaking the circuit. Small amounts of current can be dangerous.

Ÿ Use caution when working above 60V DC or 30V AC RMS. Such

voltages pose a shock hazard.

Ÿ When using the probes, keep your fingers behind the finger guards on

the probes.

Ÿ Measuring voltage which exceeds the limits of the multimeter may

damage the meter and expose the operator to a shock hazard. Always

recognise the meter voltage limits as stated on the front of the meter.

Ÿ Never apply voltage or current to the meter that exceeds the specified

maximum:

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 CAUTION symbol indicates a potentially hazardous

situation, which if not avoided, may result damage to the

product.

This symbol advises the user that the terminal(s) so marked

MAX

must not be connected to a circuit point at which the voltage

with respect to earth ground exceeds (in this case) 500 VAC

500V

or VDC.

This symbol adjacent to one or more terminals identifies

them as being associated with ranges that may, in normal

use, be subjected to particularly hazardous voltages. For

maximum safety, the meter and its test leads should not be

handled when these terminals are energized.
