The QUANTA Q9000A DC voltmeter and Q9000B DC ammeter are ±9,999-count versions of the ±1,999-count Q2000A and Q2000B, respectively. They provide the same features and benefits (but no LCD display option), plus addi-tional resolution required for many applications. A 1/8 DIN case with screw terminals for signal and power is standard. A wide range of options are available.

POWER OPTIONS
Six types of meter power are available: 120 V ac, 240 V ac, 24 V ac, 5 V dc, isolated 9-32 V dc or 26-56 V dc.

ANALOG OUTPUT OPTIONS
A 0.1 mV/count (±1 V full-scale) analog output is stan-dard and is ideal for driving a strip-chart recorder. An additional analog output can be provided by an optional vertical plug-in board. Available output signals are 0-5 V dc, 0-10 V dc, 0-1 mA (source or sink), and 4-20 mA (source or sink). The top and bottom of each output range can be scaled to fit a user-selected display span.

CONTROL OUTPUT OPTIONS
Additional outputs can be provided by a horizontal upper board. Available options include single-setpoint control with one 10 A relay, dual-setpoint control with two 10 A relays, 4-20 mA proportional control (source or sink), time-proportional 2 A solid-state relay control, and isolated, parallel BCD output. For additional information, please refer to the QUANTA and Mechanical sections.
