When you test temperature changes of the object relative to the base value, the meter may be ad-
justed to show these deviations. To do this, set the reference temperature:

use F1 F2 F3 F4 buttons to select OFFSET ,

set the required temperature offset value:

use
◄► arrows to select segment for editing,

use
▲▼ arrows to set the desired value,

select OK .
6.4 Measurement of frequency or % of duty cycle (pulse filling indi-
cator)
To perform the measurement:

set the rotary switch at Hz% ,

select MENU and use arrows and F1 F2 F3 F4 buttons to set one of three modes:

Hz frequency measurement

Hz,% frequency measurement and % of the duty cycle

connect black test lead to COM terminal and red test lead to V
Ω
CAP Hz% Temp terminal,

contact the tips of test probes to the points of measurement; red probe should be applied to the
point of higher potential,

read the measurement result on the display,

after completing the measurements, remove test leads from the terminals of the meter.
6.5 Measurement of resistance
WARNING:
Do not perform measurements on the circuit under the voltage. Before the measurement dis-
connect the power and discharge capacitors.
To perform the resistance measurement:

set the rotary switch at
Ω
CAP ,

select MENU and use arrows and F1 F2 F3 F4 buttons to set Ohms ,

connect black test lead to COM terminal and red test lead to V
Ω
CAP Hz% Temp terminal,
