Input Voltage Range is zero to 300 volts peak-to-peak in 9 ranges with full scale readings of 30 mV, 100 mV, 300 mV, 1 V, 3 V, 10 V, 30 V, 100 V, and 300 V. The meter does not respond to DC inputs. Maximum DC input is 200 V as set by the rating of the input coupling capacitor.
Frequency Response is -3 dB at 5 Hz and 50 kHz. There is an internal lowpass filter with a cutoff frequency of 50 kHz to minimize the effects of high frequency noise from the input amplifiers. Less than 3% waveform variation between sine, triangle and square wave inputs.
Input Impedance is 1 Megohm on all ranges. The analog display is a 2 inch panel meter with two scales: zero to 1 and zero to 3. The non-linearity is less than 5% of reading. The analog meter voltage is buffered and appears on a rear panel connector: zero to +3 VDC on all ranges. The non-linearity is less than ± 0.5% of reading. Female BNC connector for input on front panel. Female BNC connector for DC output and 2.5 mm male power input connector on rear panel.
Power is 18 VAC wall transformer (supplied) plugs into any (US) standard 115 VAC, 60 Hz outlet. Transformers for other mains voltages and outlets available on special order.
