Frequency measuring
•
Connect the measuring wire or the shielded cable to
the „COM” and „V/ Ω/Hz” connectors.
•
Set the function switch to „1 MHz” position and
touch the wires to the signal source.
Note:
•
Do not measure frequency at a voltage exceeding 250V RMS!
•
In noisy environment it is advised to use a shielded cable for
measuring small values.
•
Avoid touching the circuit when measuring high voltage!
Data hold function
•
Pressing the „HOLD” button the displayed value on
the screen gets held. To turn the function off press
the button again.
Automatic power off and standby
•
15 minutes after the last measurement the device
powers off automatically.
•
Press long the „Power” button when the device is on,
and the automatic power off function switch off.
Backlight
•
Press long the „B/L” button to backlight on, the light
switch off automatically after 10sec.

When measuring 36 V DC / 25 V AC voltage make
sure that the wires are not connected to a current
measuring connector and that the function
switch is not in resistance or diode measuring
mode. Always check if you have connected the
wires into the proper connectors.
•
Be careful when measuring voltage above 50V,
especially with high voltage equipment.
•
Avoid connecting to "live" circuits.
•
Turn off the power in the circuit before
connecting the multimeter to measue current
and do not measure above 20A.
•
Before measuring resistance and diode make sure
the circuit is not under power.
•
Only replace fuses to the same type and value.
•
When replacing the fuse or battery make sure all
external power sources are turned off and that
the multimeter is turned off as well.

Maintenance
Handling
•
Keep the multimeter dry. If it is exposed to
moisture wipe it dry immediately. Liquids may
corrode the circuits.
•
The multimeter must only be used at normal
temperatures. High temperatures decrease the
lifetime of electronic devices, damage batteries
and distort and damage plastic parts.
•
Handle the multimeter with care. A drop may
damage the circuits and the case which may
cause incorrect operation.
•
Protect the multimeter from dust and other dirt
that may cause premature abrasion.
•
Clean the multimeter with a wet cloth. Do not
use chemicals, solvents or strong detergents
for cleaning.
Battery replacement (1 x 9V)
•
Disconnect any external circuits from the
device. Turn the multimeter off and remove the
measuring wires from the connectors.
•
Unscrew the screw at the bottom and remove
the bottom cover.
•
Remove the depleted battery and replace it to
a new one of the same type.
Fuse replacement
•
Disconnect any external circuits from the
device. Turn the multimeter off and remove the
measuring wires from the connectors.
•
Unscrew the screw at the bottom and remove
the bottom cover.
•
Replace the melted fuse to one of the same
type and value (5x20 mm, 200 mA / 250 V „F”
type)
