TEST EQUIPMENT RISK ASSESSMENT (UK RECOMMENDATION)
Users of this equipment and/or their emplo
y
ers are reminded that Health and Safet
y
Le
g
islation require them to
carr
y
out valid risk assessments of all electrical work so as to identif
y
potential sources of electrical dan
g
er and risk
of electrical injur
y
such as from inadvertent short circuits. Where the assessments show that the risk is si
g
nificant
then the use of fused test leads constructed in accordance with the HSE
g
uidance note GS38 “Electrical Test
Equipment for use b
y
Electricians” should be used.
NOTE :
Particularl
y
on the 300mV ran
g
e the displa
y
ma
y
fluctuate even with no test leads connected. If this hap-
pens and
y
ou suspect the readin
g
s shown on the displa
y
are not correct, short the "V-
è
-

" and the "COM" input
terminal to
g
ether and check that the meter shows a readin
g
of "0".
3.3 Measuring current (µA, mA and A)
1. Plu
g
the red lead into the "µA mA" or the 10A input terminal and the black lead into the "COM" input terminal .
2. Turn the function switch to "µA", "mA" or "A".
3. A.c. currents can be measured b
y
pressin
g
the "AC/DC" button.
4. Appl
y
the probes to the circuit to the measured.
