Generator and Counter Mode

Resolution:

A. 0.1 Hz: 10–999.9 Hz

B. 1.0 Hz: 1000 Hz–20,000 Hz

Readout has automatic scale ranging.

Fast update rate of one reading per second (one second gate time)

Generator Mode

• Generates continuously adjustable frequency signal from 10 Hz to 20,000 Hz.

• One second gate time (update rate of reading) in both ranges.

• Output is a square wave, DC-coupled, nominal amplitude of 10 volts peak-to-peak, short

circuit proof. Enables calibration of Dynalco self-powered tachs, trips, etc.

Counter Mode

• Any input signal amplitude from 50 mVrms–50 Vrms

• Insensitive to signal amplitude. Responds only to frequency

• Waveform: Sinusoidal, square, triangular, or pulse

• Crystal controlled accuracy of readout

• Unipolar or bipolar since the input amplifier is AC coupled

Low Battery Indication

and a decimal point after the third digit.

1 :1:7.5 9

General information

• Power: Single 9-volt radio battery.

• For intrinsic safety use only:

Eveready 1222, Mallory M1604HD2, or Ray-0-Vac D1604

batteries.

• Intrinsic safety: All circuits and electrical components operate at low energy levels

incapable of releasing sufficient electrical or thermal energy—under normal or abnormal

conditions—to cause ignition of hazardous atmospheric mixtures of pentane, ethylene, or

methane in their most volatile state.

Battery Replacement

• Snap-open plastic door in rear of F-16 gives quick access to 9 volt battery.
