VOLTAGE

Three DC and AC Ranges:

• 150, 300, and 600 Volts DC and Volts rms.

Remote Voltage Sensing:

• Differential input - 110 dB CMRR.

• Maximum of 30 Volts peak, volts low terminal

to amps output terminal.

CURRENT

Three DC and AC Ranges:

• 5, 25 and 100 Amps DC and Amps rms.

METER IMPEDANCE

Voltage, DC or AC:

• 3 Megohm load on each voltage range.

Current, DC or AC Ranges:

• 0.016 Ohm shunt resistance for 5 Amp range.

• 0.003 Ohm shunt resistance for 25 Amp ranges.

• 0.001 Ohm shunt resistance for 100 Amp range.

RESOLUTION

Processing resolution is 16 binary bits.

Voltage Display Resolution:

• All ranges

< 9.999 V is ± 0.001 Volt.

• Ranges

> 10 V and < 99.9 V is ± 0.01 Volt.

• Ranges

> 100 V is ± 0.1 Volt.

Current Display Resolution:

• All ranges

< 9.999 A is ± 0.001 Amp.

• Ranges

> 10 A and < 50 A is ± 0.01 Amp.

Power Display Resolution:

• Better than 0.015 % of the product of the active

Voltage and Amperes ranges.

GPIB: Amps, Volts and Watts

• Same as display resolution.

ISOLATION

1500 Vrms break down from input circuit to chassis

(ground).

DISPLAY AUTO ZERO

When the A and V display indication is less than 0.5 %

of range, the displayed value is set to ZERO. Refer to

Section 5 - CT/PT Installation to disable the AUTO

ZERO function.

ANALOG OUTPUTS

This is an optional feature.

Analog AMPS, VOLTS and WATTS output signals

are DC proportional signals of 5.00 volts at full scale,

for each AMPS, VOLTS and WATTS range. Ripple is

less than 5 millivolts. The outputs are low impedance

operational amplifiers <1 Ohm and <4 milliamperes

current capacity. Each monitor signal and the common

are electrically isolated from the monitored circuits.

Isolation voltage is 750 Volts continuous and 2500 Volts

test breakdown. Leakage current is less than 0.3 micro

Amps at 240 Vrms, 60 Hz. Vrms

DATA ACQUISITION

ANALOG

The conversion of true rms to DC is expressed as:

rms

≡

()

vtdt

∫

• Rms to DC conversion averaging time constant:

Volts and Amps time constant TC ≅ 60 msec.

Watts time constant TC ≅ 120 msec.

Watts = V × I × cos θ (instantaneous)
