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.
NOTE: The meter will be Auto ranging for this function. If you wish to measure with
Manual range, follow instructions described in Section 9. For manual ranging, start at
the highest range and work down.
➔ Set the function switch to DC V.
➔ ʻmVʼ appears on the display and the LED next to
jack turns on.

➔ 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 minus (-) sign appears it
means the voltage is negative at
the point being measured.
➔ If ʻOLʼ appears on the display, it indicates over-range. Immediately re-
move 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.
NOTE: The meter will be Auto ranging for this function. If you wish to measure with
Manual range, follow instructions described in Section 9. For manual ranging, start at
the highest range and work down.
➔ Set the function switch to AC V.
