NOTE:
Comes in both a solid state version and an older vacuum tube version
This is a versatile general purpose instrument that measures dc voltages from 15mV to 1500V, dc from 1.5 micro A to 150 mA full scale and resistance from 0.2 ohms to 1500M ohms.
====================================================
DC Voltmeter
Voltage Ranges: ±15 mV to ±1500 V full scale in 15, 50 sequence (11 ranges).
Accuracy: ±2% of full scale on any range.
Input Resistance: 100 megohms ±l% on 500 mv range and above.
10 megohms ±3% on 15 mV, 50 mV, and 150 mv ranges.
DC Ammeter
Current Ranges: ±1.5 to ±150 mA full scale in 1.5, 5 sequence (11 ranges).
Accuracy: +/3% of full scale on any range.
Input Resistance: Decreasing from 9 K ohms on 1.5 scale to approximately 0. 3 Ω on the 150 ma scale.
Special Current Ranges: ±1. 5, ±5, and ±15 nanoamps may be measured on the 15, 50, and 150 millivolt ranges
using the voltmeter probe, with ±5% accuracy and 10 megohm input resistance.
Ohmmeter
Resistance Range: Resistance from 10 ohms to 10 megohm center scale (7 ranges).
Accuracy: Zero to midscale: % of reading or % of midscale, whichever is greater. % from midscale to scale value
of 2. % from scale value of 2 to 3. % from scale value of 3 to 5. ±10% from scale value of 5 to 10.
Amplifier
Voltage Gain: 100 maximum.
AC Rejection: 3 db at 1/2 cps; approximately 66 db at 50 cps and higher frequencies for signals less than 1600 v peak or 30 times full scale, whichever is smaller.
Isolation: Impedance between common and chassis is >10 meg in parallel with 0. 1 . Common may be floated up to 400 v dc above chassis for dc and resistance measurements.
Output: Proportional to meter indication; 1. 5 v dc at full scale, maximum current, 1 ma.
Output Impedance: Less than 3 ohms at dc.
Noise: Less than 0. 5% of full scale on any range (pp).
DC Drift: Less than 0.5% of full scale/year at constant temperature. Less than 0.02% of full scale
Overload Recovery: Recover from 100:1 overload in <3 sec.
AC Voltmeter
Ranges: 0. 5 v full scale to 300 v in 0. 5, 1.5, 5 sequence (7 ranges).
Accuracy: +/3% of full scale at 400 cps for sinusoidal voltages from 0. 5 to 300 v rms. The AC Probe responds to the positive peakaboveaverage value of the applied signal.
Frequency Response: +/2% from 100 cps to 100 Mc (400 cps ref.) % from 20 cps to 100 cps and from 100 Mc to 700 Mc.
Frequency Range: 20 cps to 700 Mc.
Input Impedance: Input capacity 1. 5 pf, input resistance >10 megohms at low frequencies. At high frequencies impedance drops off due to dielectric loss.
Safety: The probe body is grounded to chassis at all times for safety. All ac measurements are referenced to chassis ground.
Meter: Individually calibrated taut band meter. Responds to positive peakaboveaverage. Calibrated in rms volts for sine wave input.
