When measuring AC Voltage > 750 V, DC Voltage > 1000 V,
AC/DC mA > 400.0 mA, AC/DC A > 10 A, the buzzer will
keep sounding as the overload warning.
Approximate 1 minute before the meter is auto power off,
the buzzer will raise constantly 5 sounds to warning.
Before the meter is power off, the buzzer will raise one long
sound to warn the user.

13 Frequency & Duty Cycle Measurement
13.1 Frequency Measurement
Set the function selector switch to VAC and press Hz/%
key, as shown on page 20.
The frequency measurement mode is activated. “Hz” symbol
is displayed on the LCD. The digital display is expanded to
9999 digits. Only the auto mode is possible, no manual
range is possible.
13.2 Duty Cycle Measurement
With duty cycle measurement, we can determine the ratio
of pulse duration to cycle time of recurring square wave
signals. The duty cycle that is the percentage pulse duration
of signal is displayed on LCD i.e.
Duty cycle (%) =
pulse duration
cycle duration
X 100
Note : The applied frequency must remain constant during
the duty cycle measurement.
Set the function selector switch to VAC and press
Hz/% key twice as shown on page 20.
The Duty cycle (%) mode is activated. “%” symbol is
displayed on LCD.
15.
NOTE : Hz/% key is only applicable for VAC.

14 Temperature Measurement
Multimeter allows you to measure temperature with K-type
0 0
thermocouple (NiCr-Ni) in the range 0 C to +1300 C.

Set the function selector switch to “ C ”.
Connect the sensor as shown below.
Connections are made the same way as for Voltage
measurement
measuring range for duty cycle and maximum allowable
voltage can be found in chapter “Specifications”.

Be absolutely certain that only the specified fuses
as above are used. The use of fuse with different
specifications may place the operator, the system
& measuring instrument in danger. The use of
repaired fuses or short-circuting of the fuse holder
is prohibited.
