RELATIVE BUTTON
The relative measurement feature allows you to make measurements relative to a stored
reference value. A reference voltage, current, etc. can be stored and measurements made in
comparison to that value. The displayed value is the difference between the reference value and
the measured value.
1.
Perform any measurement as described in the operating instructions.
2.
Press the RELATIVE button to store the reading in the display and the "
REL
" indicator will appear
on the display.
3.

AC or DC Voltage Measurements
1.
Insert the black test lead banana plug into the negative
COM
jack and the red test lead
banana plug into the positive
V
jack.
2.
Turn the rotary switch to the
VDC/AC
position.
3.
Press the
MODE

Note: Pressing the
Hz/%
button while in the voltage function will switch the display to frequency
or duty cycle
AC or DC Current Measurements
CAUTION
: Do not make current measurements on the 20A scale for longer than 30
seconds every 15 minutes. Exceeding 30 seconds may cause damage to the meter and/or the test
leads.
1. Insert the black test lead banana plug into the negative
COM
jack and the red test lead banana
plug into the;
1.
Positive
uA/mA
jack for currents to 400mA
2.
Positive
20A
jack for currents to20A
3.
Turn the rotary switch to the uA, mA or A position.
4.
Press the
MODE
button to select AC or DC current
5.
