“it does everything a hvac or maintenance tech would need. out of 12 guys i work with 9 of them had the 324” - thomas

• rugged, reliable basic true-rms clamp meter
• measure ac current up to 400 a, ac/dc voltage to 600v
• measure resistance up to 4kω, continuity detection ≤ 30ω
• additions from 323 clamp: temperature, capacitance, backlight
