AEMC 6503 Hand Cranked Megohmmeter 1000V DC measurement tool

SKU CH-QGW5-01G1B MPN 6503

Hand-cranked megohmmeter tests insulation resistance up to 5000 megohm at 250, 500 or 1000 V DC with live-circuit detection to 600 V and CAT II 600 V safety rating

  • Analog/digitalDigital
  • Product typeElectronic
  • Hand-crank power enables testing where no batteries or mains exist
  • Three selectable test voltages 250, 500 and 1000 V DC cover diverse insulation checks
  • Measures insulation resistance from 1 to 5000 megohm for cables, motors and switchgear
  • Live-circuit detection up to 600 V AC/DC warns before a test begins
  • CAT II 600 V and CAT III 300 V safety ratings protect the operator in plant environments

Hand-cranked insulation tester

The AEMC 6503 is a hand-cranked megohmmeter that generates its own test voltage, so it operates on remote sites where batteries or mains power are unavailable. It provides selectable DC test voltages of 250, 500 and 1000 V for insulation resistance measurement up to 5000 megohm. A live-circuit detector warns of voltage up to 600 V AC or DC before testing begins. The analog display delivers 2 percent full-scale accuracy.

Field maintenance and acceptance testing

Technicians performing acceptance testing or preventive maintenance on wiring, cables, switchgear and motors in the field will appreciate the crank-powered independence. The CAT II 600 V and CAT III 300 V safety ratings cover typical plant environments. Users who need digital readouts, data logging or automated test sequences should consider other instruments. Laboratories requiring higher test voltages or tighter accuracy specifications will also need a different solution.

Crank-generated test voltage

The defining characteristic is the hand-crank power source that produces the 250, 500 and 1000 V DC test voltages without any external supply. This makes the 6503 suitable for locations where battery replacement or AC power are impractical. The three color-coded leads and soft carrying case complete the field-ready kit.

Questions about this item

What test leads and accessories are included so I can start insulation resistance testing right away?

The package includes three colour‑coded leads with matching alligator clips, a black test probe and a soft carrying case for field use.

How does the hand‑cranked 6503 behave when I also need to check live circuits up to 600 V AC or DC?

It detects live voltage from 0 to 600 V AC/DC before you crank, so you can verify a circuit is dead before applying the 250, 500 or 1000 V DC test voltages.

After cranking and selecting a test voltage, how do I confirm the megohmmeter is reading correctly?

The analog display shows the insulation resistance from 1 to 5000 megohm with 2 % full‑scale accuracy, and the auto‑ranging function selects the appropriate scale automatically.
