5. Making measurements
Preparatory steps and directions to be followed
1. After you switch the meter on, wait for 30 seconds before you make the first measurement.
2. You must set the desired function with the rotary switch before you bring the probes into contact with the item to be meas-
ured. Remove the probes from the item to be measured before you change the setting of the rotary switch.
3. If the meter is used in the vicinity of equipment which generates electromagnetic interference, the display may become
unstable or incorrect measurements may be shown.
4. Keep the meter dry.
TEST EQUIPMENT RISK ASSESSMENT (UK RECOMMENDATION)
Users of this equipment and/or their employers are reminded that Health and Safety Legislation require them to carry out valid
risk assessments of all electrical work so as to identify potential sources of electrical danger and risk of electrical injury such
as from inadvertent short circuits. Where the assessments show that the risk is significant then the use of fused test leads
constructed in accordance with the HSE guidance note GS38 'Electrical Test Equipment for use by Electricians' should be
used.
6. Measurement procedure
The meter was produced and tested to comply with the requirements of IEC publication 1010, "Safety requirements for electri-
cal measuring equipment" and with UL 1244 and was in a reliable state when supplied.
This operating manual gives directions and warnings which it is essential for the user to follow if he is to work safely and the
safety of the meter is to be ensured.
Measuring voltages
WARNING : Never apply voltages of more than 600Vd.c. or 600Va.c. to the inputs of the meter. Never apply voltages of more
than 600Vd.c. or a.c. rms to earth to the input terminals of the meter; if these voltages are exceeded, there is a
risk of electric shocks or damage to the meter.
When making measurements on circuits carrying high voltages, take particular care not to touch live parts.
