The Q2000H and Q9000H are frequency meter/tachometers with extensive zero and scale factor adjustment capability for direct readout in engineering units for RPM, flow and speed. Input frequencies can be as low as 100 Hz or as high as 20 kHz for the display maximum, which is 1,999 for the Q2000H and 9,999 for the Q9000H. Zero offset is available for use with transducers with a frequency output and a live zero.

EASY TO INTERFACE
The Q2000H and Q9000H are designed for easy interfacing to transducers with a frequency or pulse output. These include turbine flowmeters, passive magnetic pickups, and active proximity detectors with NPN, PNP or NAMUR (1 mA/3 mA) output. To accommodate different signal levels and provide noise immunity, the DC trigger level can be adjusted from 1 to +5 V, and two hysteresis levels are selectable. Signals as low as 15 mV p-p or as high as 130 V rms can be monitored directly.

CONFIGURATION AND CALIBRATION
The price of the Q2000H or Q9000H includes configuration and calibration, normally provided by an authorized Newport distributor. The units can also be configured and scaled in the field. Adjustments for zero, span, and trigger level are accessible from the front panel to allow final calibration or recalibration without removal of the meter from the panel.

POWER AND DISPLAY OPTIONS
Six types of meter power are available: 120 Vac, 240 Vac, 24 Vac, 5 Vdc, isolated 9-32 Vdc and isolated 26-56 Vdc. An LED display is standard. An LCD display is available with the Q2000H and is ideal for viewing in bright ambient light.

The QUANTA Q2000H OR Q9000H Can be scaled to read RPM directly. With the dual-setpoint controller(optional), they can provide under and overspeed alarms. The 1 mV/count analog output (standard) can be used to drive a strip-chart recorder for permanent.

ANALOG OUTPUT OPTIONS
An analog output which tracks the display is standard and is useful 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 Vdc, 0-10 Vdc, 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.
