OPERATING INSTRUCTIONS
This meter comes with an exclusive patented technology featuring bright
LEDs indicating the correct input jack to plug-in the positive (red) test lead
for the selected function. The LED turns off after the test lead is completely
plugged in the correct jack. If the test lead is plugged in the wrong jack, the
LED will start flashing and the buzzer will start beeping.
1. DC VOLTAGE MEASUREMENT
WARNING
: MAXIMUM INPUT IS 1000V DC. USE EXTREME CAUTION WHEN WORKING
WITH HIGH VOLTAGES. NEVER APPLY THE TEST LEAD TO THE MEASURING CIRCUIT WHEN
CHANGING THE POSITION OF THE FUNCTION SWITCH. IF YOU ARE UNSURE OF THE VOLTAGE
BEING MEASURED, SELECT THE HIGHEST RANGE AND REDUCE UNTIL A SATISFACTORY
READING IS OBTAINED.
➔
Set the function switch to 1000 on the DC VOLTS scale.
➔
The LED next to V/ /F/ / jack will turn on.
➔
Plug the red test lead in V/ /F/ / jack and
the black test lead in jack.
➔
Apply the test leads to the circuit to be
measured. Ensure that the black
lead is connected to the negative
side of the circuit and red lead to
the positive.
➔
Read the displayed voltage.
➔
If the reading displayed does
not have a sufficient number of
digits i.e. 00.2 Instead of 1.786,
set the function switch to the next
lower range. Repeat until you have
maximum digits possible without
displaying ʻIʼ.
➔
If the minus (-) sign appears it means the voltage is negative at the
point being measured.
➔
If ʻIʼ appears on the display, it indicates over-range. Immediately remove
test leads from the measuring circuit to avoid any damage to the meter.
The input voltage should not exceed the measurement capability of this
meter.
