Digital Multimeter

INTENDED USE

- Digital clamp meter BORT BMM-750C is an appliance 

with a wide range of functions for everyday use:
- Measurement of direct voltage DCV ()
- Measurement of alternating voltage ACV (V ~)
- Measurement of alternating current (without breaking 

the circuit) ACA (A ~)
- Measurement of electrical resistance (Ω)
- Continuity check / wire identification ()
- Data capture “DATA HOLD” . To fix the measurement re-

sult, press the button and the current reading will be fixed 

on the display . Press the button again to reset the locked 

value .
- Insulation resistance check (when connecting an addi-

tional 500-volt insulation meter) (Ω)

Product elements (fig. 2)

1. 

Clamp meter . It is used for non-contact measurement 

of alternating current flowing through a conductor .

2. 

The trigger . Pressing the trigger opens the ticks . By re-

leasing the trigger, the ticks will close again .

3. 

Data capture button .

4. 

Rotary switch of functions and ranges . Clamp meters 

do not work when the switch is set to the “OFF” position .

5. 

Liquid crystal display, 3 ½ digit (maximum value 1999) . 

Display of measurement result, decimal point, polarity, 

overload, battery discharge .

6. 

The “EXT” input jack is used when connecting a 500-volt 

insulation tester (tester not included) .

7. 

COM input jack for connecting a negative polarity 

probe (black probe) .

8. 

V / Ω input jack for connecting a positive polarity probe 

(red probe) .

9.

 Battery compartment (on the back of the device) .

Contents of delivery

- Digital multimeter;
- The probe with a red cable;
- The probe with a black cable;
- Battery;
- A bag .

Product Life

The product lifetime is 10 years .

Shelf life

Shelf life is unlimited, if the storage conditions are ob-

served .

Storage conditions

Products must be stored in dry, ventilated warehouses at 

temperatures from 0 °C to + 40° C with a relative humidity 

of not more than 80% .

Transportation

It is categorically not allowed to drop and any mechanical 

effects on the packaging during transportation .
During unloading / loading, it is not allowed to use any 

type of equipment that works on the principle of packing 

clamping .

SAFETY WARNINGS

WARNING! Measuring high voltages and currents 

poses a life hazard . Never touch exposed metallic 

parts of the instrument leads .

•  The multimeter is sensitive . Protect it from vibrations 

and do not let it fall down .
•  If the multimeter is not going to be used for a time, 

please switch it OFF to save on batteries .
•  If the multimeter is not going to be used for a long peri-

od, remove the battery in order to avoid spilling .
•  Do not subject the device to high humidity or high tem-

peratures .
•  Keep the multimeter away from strong magnetic fields .
