Voltage Tester for 12–690 V DC

The Westward 28AF75 is a digital multimeter designed for technicians who need to verify DC voltage presence across a wide 12 to 690 volt range. It uses a probe tip connection and runs on battery power with auto-ranging to simplify measurements. The LCD screen presents readings clearly for electrical troubleshooting tasks.

Measurement range and continuity limit

The tester covers DC voltages from 12 V up to 690 V and confirms continuity at 400 kiloohm. It operates at a calibration frequency of 50 to 60 Hz. The fixed continuity threshold means circuits with resistance above 400 kiloohm will not register as continuous, limiting use on very high-impedance paths.

400 kiloohm continuity threshold

The single specification that decides suitability is the 400 kiloohm continuity confirmation level. Buyers who need a lower resistance threshold for sensitive continuity checks cannot use this tester. The fixed 400 kiloohm setting determines whether the tool matches the application.

Questions about this item

Will the 400 kiloohm continuity check work with my existing 12V automotive circuits?

Yes, the tester measures continuity up to 400 kiloohm and covers 12 to 690V DC, so it handles standard 12V vehicle wiring.

How can I confirm the LCD is showing correct readings after I power it on?

The auto-ranging LCD updates automatically; verify a known live source between 12 and 690V DC and check that the display changes without manual range selection.

Does the box include the battery needed for the probe tip tester, or must I buy it separately?

The product runs on battery power; the supplied battery is included so the unit is ready to use straight away.
