Fluke 1662 Installation Tester

Fits electrical installation verification where you need voltage/frequency, insulation, continuity, loop/line, RCD A/AC, PEFC/PSC, and phase sequence in one handheld — without earth-resistance or Type B / EV RDC-DD functions.

Key advantages

• Core EN61557 install tests — Voltage, insulation, continuity, loop/line (no-trip & high-current), RCD A/AC, PEFC/PSC, phase sequence.
• 300 V CAT IV / 500 V CAT III — IEC 61010-2-030 category marks.
• Basic 1660-series package — Handheld 1.3 kg class with dual backlit display.
• Optional DMS download — PC result handling when specified.

Typical applications

• Residential and light-commercial installation verification on A/AC RCD circuits.
• Electricians who need loop/line and insulation without earth resistance or Type B / EV RCD.
• Fleets standardizing on Fluke 1660-series basic testers.

Selection guide

• Functions — AC voltage to 500 V; insulation; continuity; loop/line impedance (no-trip & high-current); RCD trip time/current (A/AC); PEFC/PSC; phase sequence.
• Accuracy — Per EN61557 and Fluke 166x Users Manual specification tables (function-dependent).
• Supply — 6× AA alkaline IEC LR6 (usable with 1.2 V NiMH).
• Electrical connection — Detachable 4 mm leads; country-specific mains cord; zero adapter.
• IP — IP40 (IEC 60529).
• Ambient — Operating −10…+40 °C; storage −10…+60 °C (battery-limited); operating altitude 2000 m.
• Display — Dual display with backlight.
• Communication — PC download via DMS (optional).
• CAT / safety — IEC 61010-1 Pollution Degree 2; IEC 61010-2-030 300 V CAT IV / 500 V CAT III; EN61557-1/-2/-3/-4/-5/-6/-7/-10 (model-dependent earth/phase); IEC 61326-1 Portable.
• Mounting — Handheld / portable installation tester.
• Weight / size — 1.3 kg (with batteries); 10.0 × 25.0 × 12.5 cm.

Common mistakes

• Ordering 1662 when earth resistance, L-N/N-PE continuity inputs, Type B smooth-DC RCD, or EV 6 mA RDC-DD are required — those are on 1663 (SKU 43384).
• Ignoring CAT limits (300 V CAT IV / 500 V CAT III) for the distribution system under test.
• Expecting IP66 plant sealing — rating is IP40.
• Assuming DMS PC download is included without ordering the optional software path.
• Using outside −10…+40 °C operating ambient without checking battery-limited storage limits.

When to RFQ / what to tell us

1. Required tests (insulation, loop no-trip vs high-current, RCD A/AC, PEFC/PSC, phase sequence).
2. Confirm you do not need earth resistance / Type B RCD / EV 6 mA RDC-DD (else select 1663).
3. Mains cord country variant and lead set needs.
4. DMS / PC download requirement.
5. Quantity, ship-to country, spare battery preference (6× AA / NiMH).

FAQ

Q: Which installation tests does 1662 cover? A: AC voltage to 500 V, insulation, continuity, loop/line (no-trip & high-current), RCD A/AC, PEFC/PSC, and phase sequence. Accuracy is function-dependent per EN61557 / users manual tables.

Q: Does it do earth resistance or Type B / EV RCD? A: Not on 1662. Those functions are on Fluke 1663 (SKU 43384). Confirm the function list before RFQ.

Q: What CAT rating applies? A: IEC 61010-2-030 300 V CAT IV / 500 V CAT III. Match to the distribution system under test.

Q: What should I send for a quote? A: Required functions, cord country, DMS need, quantity. Compatible with workflows using Fluke 1662 — we do not claim authorized-dealer status.
