OPERATING INSTRUCTIONS

CALIBRATE FREQUENCY INPUTS

Choose this function to provide pulses into frequency measuring instruments. The 830-KP output is a zero crossing square wave from -1V to +5V amplitude. Available ranges are from 0.01 to

10.00kHz, 1 to 1000 Hz and from 1 to 1000 CPM (Counts-Per- Minute).

CPM is used to simulate extremely slow frequency signals with greater resolution. For example, 10 Hz is equivalent to 600 CPM. To convert from CPM to Hz Divide by 60. To convert from Hz to CPM multiply by 60.

1)Disconnect one or both input wires from the device to be calibrated

2)Press the FREQUENCY/PRESSURE pushbutton until any frequency signal (KHz, Hz or CPM) appears on the display.

3)Press the DISPLAY/SOURCE/READ push-button until SOURCE and KHz, Hz or CPM appear on the display

4)Press the TYPE/ENG UNITS pushbuuton to select between KHz, Hz or CPM on the display

5)Connect the red SOURCE lead of the calibrator to the plus (+) input of the device and the black SOURCE lead to the minus (-).

Output frequency is continuously adjustable with the UP/DOWN push-buttons. Zero & Span (or any other values) are available by using the LO and HI "QUIK-CHEKs"

OPERATING INSTRUCTIONS

READ FUNCTIONS

Select read by pressing the DISPLAY/SOURCE/READ pushbutton until the word READ appears on the LCD display. The READ functions measure the desired signal. Multiple scales are available for some functions.

MIN/MAX

To read the Maximum or Minimum INPUT since READ mode was entered, simply press the MAX or MIN push-button. The value will appear on the LCD along with the word MAX or MIN. The MAX/MIN values are automatically updated and may be viewed at any time without interrupting the other values.

RESTARTING MIN/MAX

Pressing the STORE/RESET push-button will cause the 830-KP to store the present reading into the MAX and MIN memories. Upon releasing the STORE/RESET push- button the 830-KP will resume reading the input and update the MAX & MIN values as the measured signal changes.

OUT OF RANGE SIGNALS

OVER

Signals above or below those available for

the currently selected range will be indicat-

UNDER

ed by OVER and UNDER on the display.
