Relative measurement mode
The meter will display relative measurement in all functions except Frequency.
To enter and exit the relative measurement mode:
1. With the meter in the desired function, touch the test leads to the circuit on
which you want future measurement to be based.
2. Press the R
RE
EL
L key to store the measured value and activate the relative
measurement mode. The difference between the reference value and
subsequent reading is displayed.
3. Press the R
RE
EL
L key for more than 2 seconds to return the meter to normal operation.
3.2 Measurement Functions
AC and DC Voltage measurement
To avoid electrical shock and/or damage to the multimeter, do not
attempt to take any voltage measurement that might exceeds
1000V DC or 1000V AC rms.
To avoid electrical shock and/or damage to the instrument, do not
apply more than 1000VDC or 1000VAC rms between the common
terminal and the earth ground.
The meters voltage ranges are 600.0mV, 6.000V, 60.00V, 600.0V and 1000V.
(AC 600.0mV range only exists in manual mode).
To measure ‘AC or DC’ voltage:
1. Set dial to the 'D

V' range.
2. Connect the black test lead to the C

M and red test leads to the V
V terminals
respectively.
3. Connect the test leads to the circuit being measured.
4. Read the displayed value. The polarity of red test lead connection will be
indicated when making a DCV measurement.

• An unstable display may occur especially at 600mV range, even though you do
not put test leads into input terminals, in this case, if an incorrect reading is
suspected, short the terminals in use to make the display return to zero.
• For better accuracy when measuring DC, offset from the AC voltage, measure
the AC voltage first.

• Select the AC voltage range, then manually select a DC voltage range equal
to or higher than the AC range. This improves the accuracy of the DC
measurement by ensuring that the input protection circuits are not activated.
