TAKING MEASUREMENTS:

CAUTION:
1. If there is no display or "
replace the battery ASAP.
2. Never exceed the maximum input voltage or current limits shown besides the input
jacks " ", otherwise the meter will be damaged and this is dangerous to life.
3. Turn the rotary switch to proper range before operating.

C-1 MEASURING DC VOLTAGE
1) Connect the black test lead to "COM" jack and red test lead to "V" jack.
2) Set the rotary switch to "V
3) Connect the test leads across with the object to be measured. LCD appears the
measuring value and also the polarity of the red test lead.
CAUTION
1) If magnitude of the voltage being measured is unknown, always start with the
highest range and reduce until satisfactory reading is obtained.
2) If "1" is shown on the LCD, which means the meter is overloaded, then set the
measuring range to a higher range.
3) " " means never to exceed the maximum input limits of 1000V, otherwise
internal circuit of the meter will be damaged.
4) Take extra care of voltage leakage when measuring high voltage.
C-2 MEASURING AC VOLTAGE
1) Connect the black test lead to "COM" jack and red test lead to "V" jack.
2) Set the rotary switch to "V~".
3) Connect the test leads across with the object to be measured.
CAUTION
1) Refer to "DC Voltage Caution" 1, 2, 4.
2) " " means never exceed the maximum input limit 750V, otherwise internal
circuit of the meter will be damaged.
" is shown on the LCD when the meter is switched on,
