To enable/disable APO
Press SELECT and RELATIVE buttons at
the same time and hold them pressed until
you hear double-beep sound.
When enabled, APO will appear on LCD.
When disabled, APO will disappear from
the LCD.
Measurement modes
Set the desired measurement by turning the dial so it points at the appropriate posi-
tion. Power off the multimeter by positioning the dial to the OFF position. Dial positions
are as follows:
• OFF: Multimeter is turned off.
V AC: AC voltage measurement.
•
• V DC: DC voltage measurement.
• Ω : Resistance, continuity, diode and capacitance measurements. Use
SELECT button to cycle through these measurement modes.
• Hz %: Frequency and duty cycle measurement. Use SELECT button to toggle
between these measurement modes.
• °C: Temperature measurement in °C or °F scale. Use SELECT button to toggle
between °C and °F measurement scales.
• A: Current measurement in 10 A range.
• mA: Current measurement in mA range.
Carrying out measurements
Commissioning
General Information to carry out measurements:
Measurements in dangerous proximity of electrical systems are only to be
carried out in compliance with the instructions of a responsible electronics
technician, and never alone.
Test leads and test probes may only be touched at handle surfaces provided.
Absolutely avoid the direct contact of the test probes. Prior to switching to a
new measurement range or a new type of measurement, remove all connections
from UUT.
Measurements have to be carried out by respecting the standards.
Voltage measurement
To avoid electrical shock, the valid safety measures and VDE directives strictly
have to be met concerning excessive contact voltage when working with volt-
ages exceeding 120 V (60 V) DC or 50 V (25 V) rms AC. The values in brackets
are valid for limited areas (such as e.g. medicine, agriculture).
