2 / 4 page METRAport3A Folding Analog Multimeter 2 GOSSEN METRAWATT GMBH Characteristic Values 1) The 100 mV to 10 V measuring ranges can also be used for current measurement in accordance with the following table (e.g. reverse current or insulation current). These measuring ranges are rated at accuracy class 5. Frequency range at ~: 15 ... 100 Hz. Same overload protection as for voltage measuring ranges. 2) Measured value = displayed value + constant, 0 dB 0.775 V, i.e. 1 mW at 600 Ω 3) Protected with PTC resistor 3) Protection by means of FF 1.6A/600V AC fuse link in combination with rectifier diodes. 4) FF 16A/600V fuse link, 10 A: max. 10 minutes Accuracy under Reference Conditions per IEC 60051/EN 60051 Class 1.5 for zero-frequency quantities, class 2.5 for periodic sinusoidal quantities and class 1.5 for resistance (intrinsic error relative to 69 mm scale length) corresponding to max. 10% intrinsic error of the measured value within the range of the exaggerated scale arc. Reference Conditions Ambient temperature +23 ° C ±2 K Relative humidity 40 ... 60% Normal position of use Instrument and scale horizontal ±1° Measured quantity frequency 45 ... 65 Hz Measured quantity waveshape Sine Battery voltage 7.5 V ±0.1 V Other influencing quantities per IEC 60051/EN 60051 Influencing Quantities and Nominal Ranges of Use Temperature +5 ... +23 ... +35 ° C Limiting temperatures For accuracy +5 ... +35 ° C For operation 0 ... +40 ° C For storage -25 ... +65 ° C (without batteries) Position Additional influence error of max. ±1% of the scale length if the scale is tilted between 0 and ±120° relative to horizontal Frequency Additional influence error of max. ±5% of full scale value in the following ranges: Auxiliary voltage No additional influence error. The upper limit must be set with the potentiometer for all measuring ranges in the case of resistance measurement. Series-mode interference voltage damping For V : > 60 dB, AC 50 Hz For V ~: > 120 dB, DC Common-mode interference voltage damping > 120 dB, DC and 50 Hz AC Other influencing quantities per IEC 60051/EN 60051 Power Supply Battery operation Nominal voltage: 9 V , 9 V flat cell battery per IEC 6LR61 (6F22), alkaline manganese, zinc-carbon or NiCd rechargeable battery. Battery service life With zinc-carbon: approx. 500 hours, with alkaline manganese: approx. 1000 hours, with NiCd: approx. 200 hours, in the Ω x 1 range: ¼ of specified service life Battery test Pointer must be within the battery test field.
