Voltage Measurement; Non-Contact Voltage Sensing; Battery Replacement - Bahco BMVAT1000 Instruction Manual

BMVAT1000

5.2 Voltage Measurement

5.2.1 Voltage and Polarity
(1) Connecting two probes to two ports of the voltage source.
(2) Press two ON / OFF buttons on two probes at same
time. Voltage and polarity will be displayed on the LCD.
(DC 6 – 1000V; AC24 – 1000V; AC / +DC / -DC).
(3) The direction of the main probe will determine DC+ or DC-.
If main probe is on the positive port, DC+ lights up, and
vice versa.
(4) CAUTION: If only one of the buttons has pressed,
error voltage value AC 23V – AC 55V will be displayed
on the LCD when voltage is greater than AC 300V.
5.2.2 High Voltage indication
LCD will display " " when voltage source
5.2.3 Phase Rotation
(1) Phase rotation measurement is only for 3 phase (4 lines)
system. Please using the right hand hold the main
probe handle (behind the barrier) properly during the
measurement (because one of the sensing area is on the
main probe handle).
(2) LCD will display voltage between phases.
(3) If the rotation is clockwise, LCD will display "R".
(4) If the rotation is counter-clockwise, LCD will display "L".
(5) Testing tips: This measurement uses tester as a virtual
ground; if equipment or user is not properly isolated, the
measurement may not function properly.

5.3 Non-contact Voltage Sensing

(1) To switch on the function, press the "LIGHT / NOT-
CONTACT SENSING SWITCH", LCD will display "DE-".
(2) Non-contact voltage indicator "
main probe will light up and buzzer will buzzing when the
sensor is near electromagnetic file greater than 90VAC.
(3) Press the "LIGHT / NON-CONTACT SENSING SWITCH"
again to switch off the function.
(4) This function will automatically switch off after 3 minutes.
5.4 Continuity
(1) CAUTION: Please make sure there is no live voltage
100VAC/ VDC.
in the circuit before continuity measurement.
(2) Connecting the two probe to the to circuit wish to test,
press both "ON / OFF SWITCH" on two probes, if the
circuit is continued, all indicator on the LCD will flashing,
and buzzer will be buzzing.
(3) CAUTION: If the circuit is continued, equipment
shall act like self-diagnostic.
5.5 Illumination
(1) Long press and hold the "LIGHT / NON-CONTACT
VOLTAGE SENSING SWITCH" to switch on the
illumination light.
(2) CAUTION: Illumination function and non-contact
voltage sensing function share the same button, please
operating these two functions carefully.

6. Battery Replacement

• WARNING: Please do not operate any functions and
move the equipment away from the voltage source when
replacing the batteries.
• If LCD flash 5 times then switch off automatically during
self-diagnostic or voltage measurement, it indicating the
equipment is run out of the battery power. Please change
the batteries.
• Battery power level will also display on the LCD during the
voltage measurement; please take caution with the battery
power level.
(1) Unlock the battery cap by a coin.
(2) Open the battery cap and replace the battery. Please
take care of the battery polarity.
