READ FUNCTIONSSelect 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/MAXTo 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/MAXPressing 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 SIGNALSSignals above or below those available for
the currently selected range will be indicat-
ed by OVER and UNDER on the display.

CALIBRATE FREQUENCY INPUTSChoose 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
10.00 kHz, 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

READ PRESSSURE
WARNING! - SAFETY CONSIDERATIONS
Sudden release of compressed or stored gas can cause personal
injury. Always vent the system before making pressure
connections or disconnections. Exercise standard physical
protection practices such as eye protection, gloves, protective
clothing, etc.
To prevent the potentially hazardous release into the atmosphere
of substances introduced into the pneumatic system by the user,
no relief valves are provided in the QuikCal 90 Pressure Module.
Consequently, if a module is overpressurized, the sensor will be
damaged.
FITTING INSTALLATIONAll pneumatic connections to the QuikCal 90 Module are made via
1/8”-27 NPT threads in the pressure port. Adapter fittings may be
used for 1/4”-18, straight 10-32 threads or any other size fittings to
match the field connections.
To install a fitting in a module pressure port:
1) Apply Teflon tape or pipe dope to the fitting threads (Teflon tape
not recommended with stainless steel fittings)
2) Carefully install the fitting in the pressure port on top of the
module
3) Use a 5/8” wrench to support the pressure module port and a
second wrench to tighten the fitting
4) Check for leaks
