LEAKAGE CLAMP METERS with COMPARATOR SK-7810/7815 are a new type of Clamp Meter for measuring Leakage Current and have advanced func­tions such as Comparator and Max/Min Measurements. SK-7810 is Manual Ranging and includes an output terminal for connection to a Recorder. SK-7815 is Auto Ranging and includes AC Voltage ranges. Both models are rugged, compact instru -ments designed to fit easily in the hand.

• EASY TO READ LCD •LOW PASS FILTER(LPF)3000 count LCD with unit and symbol display. Cuts off frequencies higher than 150Hz.

•COMPARATOR: •DISPLAY HOLD <DH)1mA to 20mA setting. Buzzer sounds when measuredvalue exceeds the set point.

Measured value is held by OH Key.

• MAX/MIN MEASUREMENTSMaximum and minimum values are stored and displayed.

•OUTPUT TERMINAL (SK-7810)Analogue output is available for recorders.

• MEASURING SPECIFICATIONS(23"C ±s"C Less than 80% RH in non-condensing)

AUTO POWER SAVE function saves battery consumption if

meter is not turned off. POWER HOLD function enables

continuous measurement for langer than 30 minutes.
