CIRCUIT DESCRIPTION -. 14 ACCESSORIES SECTION 4. ACCESSORIES M0Dm.S 160, 163 GENERAL. The Model 1601 is a combination ac-dc probe that enables the user co measure voltages from 45 HZ to 45 kHz when used with either the Model 160 or 163. me slide svitch (S101) can be used eo Select either AC mode or straight-through DC Mode. SPECIFICATIONS : -MODE: Straight-through probe does not alter any Model 160 or 163 specifications except: 1. 150 pico- farads input capacitance, 2. 0.5 ampere nlaximum current, 3. 0.3 ohm resistive offset, 4. i*o micro- volts thermal offset. AC (Voltage only): ACCURACY (400 Hz):.+l% af reading or i0.L volt, whichever is greater (rms of sine wave to dc can- “WSiO”). FREQUENCY RESPONSE: -2% at 45 Hz and 45 kllz. RANGE: 250 volts rms maximum. MAXIMUM OVERLOAD: Peak ac plus dc bias must not exceed 400 volts. INPUT IMPEDANCE: 0.5 megohm, shunted by less than 20 picofarads. OUTPUT IMPEDANCE: output: m”St he shunted by 10.2 megohms iI% for rated accuracy (Model 160 and 163 impedance on 1000, 100 and lo-volt ranges). 10% variation in the 10.2 megohms cauaea 1% additional error.
