C. Capacitance Meas urement
Warning – To a void damage to the Me te r or to t he equipm ent under t est, disco nnect circ uit po wer and
discharge all high- voltag e capa citors bef ore meas uri ng ca pacita nc e. Use the DC Voltage f unc tion to
conf irm t hat the capacito r is discharge d. N eve r att empt to input over 60 V in DC or 30V in AC to avoid
perso nal dang ero us.
The Meter’ s capa citance rang es ar e: 40.00nF, 400.0nF, 4.000

F, 40.00

F and 100.0
µ
F. To measu re c apa citance,
connect the M eter as follows:
7. Insert the red test lead into the
HzV
Ω
te r min al and the black test le ad into th e C O M ter minal.
8. Set the rot ary switch to .
9. Connect the test le ads a cross with the obj ect b eing me asured.
The me asured valu e shows on the display.
Note
l
For t esting the cap acitor with polarity, conn ect th e red test lead to anode & the black test le ad to cathod e instead .
l
To incre ase the ac cura cy o f cap acitanc e me asure ment especi ally when me asuring under 400nF, use REL mode to
auto matic ally subtract th e Mete r built-in equaliz ed c apa citance and residual capa citanc e o f test leads from the
result.
l
It takes a longer ti me when testing a high cap acitor value , the testing ti me is around 15 s econds in 100
µ
F range.
l
When capacitanc e measu re ment h as been co mpleted , disconne ct the connection between the testing leads and the
circuit unde r t est.
