OPERATING INSTRUCTIONS
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.
➔
Plug the red test lead in
V/ /mA/
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.
2. AC VOLTAGE MEASUREMENT
WARNING
: MAXIMUM INPUT IS 750V AC. USE EXTREME CAUTION WHEN WORKING
WITH HIGH VOLTAGES. NEVER APPLY TEST LEADS 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 750 on the
AC VOLTS
scale.
➔
Plug the red test lead in
V/ /mA/
jack and the black test lead in
jack.
➔
Apply the test leads to the circuit to be measured.
➔
Read the displayed voltage.
