Page 5: How To Mount The Unit
HOW TO MOUNT THE UNIT The unit is designed to be mounted with a gasket providing a water tight seal. Two mounting brackets are provided to secure the unit to the panel. A panel less than .1" may distort if the clamps are screwed too tightly. Slide the body of the unit through the rubber gasket. -
Page 6: Wiring 913 Drt
WIRING THE 913 DRT The rear terminal contains 12 screw terminals for connecting #14 to #28 gauge wire. The unit is controlled by a microprocessor and, therefore, an electrically "noisy" environment could cause operating problems. The input power line should not be common to power lines for motors, pumps, contactors, etc. -
Page 7: Typical Hookups
CONNECTING AC / DC POWER NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has been designed with an isolated AC input. Thus, polarity is not a concern for the AC input. The chassis is plastic, therefore earth ground is not used. -
Page 8: What Can You View
SELECTABLE COMBINATIONS A ADD B - Scaled A input added to the Scaled B input. A SUB B - Scaled A input subtracted by the Scaled B input. A / B - Scaled A input divided by the Scaled B input X 100 to show percent of A to B. A / A + B - Scaled A input divided by the Scaled A input plus the scaled B input X 100 to show percent of A plus B. -

The following is a list of abbreviations as they appear on the display and front panel of the unit. ABBREVIATION DESCRIPTION FACTOR SCALING FACTOR - For A and B Inputs. Each input has a separate 5 digit dividing scale factor. DP F A DECIMAL POINT FOR FACTOR A - Enter location of decimal point for scaling Factor A by pressing the button under the digit where the decimal is desired. - Page 11 Z 3600 DIVIDE K FACTOR BY 3600 - This sets the unit for rate per hour; equal to 3600 times rate per second. NOR## NORMALIZING FACTOR - Normalizes (averages) the data being received. Higher settings provide more normalizing (averaging) for a more stable display. Derived from the equation: (Old Data x "NOR"...

Page 13: Calculating Scale Factors
CALCULATING SCALE FACTORS There are two separate dividing scale factors, one for input "A" and one for input "B". The factor to enter is the number of pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999. The factor is the same for rate and count. -
