Page 12: Installation Hints For Best Performance
Installation Hints for Best Performance This section offers several suggestions which will help you get the best performance from your measurement system. Some sensors generate comparitively small signals which can easily be corrupted by the potentially high level of electrical noise which can be created by electrical machinery such as motors, welding systems, discharge lighting, AC power inverters and solenoids. - Page 13 When using multi-core screened cable to connect several displays to several sensors, please be sure to use one twisted pair for each display and sensor. Do NOT use a wire from one pair for signal positive and a wire from another pair for signal negative, as this will prevent the twisted cables form cancelling any induced electrical noise, and can couple noise from one channel to another.

Factory Defaults You can return the display to its factory default conditions whenever you wish. If you do so, you will permanently loose all your settings and will need to start from the beginning again. The calibration Audit Counter will NOT be reset, there is no way provided to reset this value, as it is intended as a secure record to indicate whether changes have been made to the display since it was last calibrated.. -
Page 20: Simple Rate Mode
Simple Rate Mode Rate mode is ideal for showing instantaneous speed, RPM, frequency, production rate, flow rate etc. For production rate showing the true number of items produced in the last hour, consider using our ‘Production Rate Mode’ method, which is ideal for production which is erratic or has periods of widely differing production rate. - Page 21 Application Notes - Rate Mode RPM Measurements We can accept any number of pulses 28664 per rotation, from 1 upwards.

Page 26: Production Rate Mode
Production Rate Mode In this mode four inputs are available, two can add to give a combined total, and two can subtract to give combined rejects. This mode of rate measurement is ideal for showing real production rates over longer periods, for example showing items per hour, for the previous hour, updated every 15 seconds, 5 minutes, or whatever best suits your process. -
Page 27: Production Rate Mode
Application Notes for Production Rate Mode 1. Choose an averaging time, in seconds, you want to use for computing your production rate. For example if you want to average over 45 minutes, your averaging time will be 2700 seconds. We need to calculate an update time for your display, we will have up to 200 samples avail- able in your averaging period. -
Page 28: Quadrature Mode
Quadrature Mode The quadrature mode allows you to scale a count and increase or decrease the value according to the sequencing of two pulses which are 90 degrees out of phase. This mode is ideal for measuring distance in pay-out/feed-in cable systems, or direction in rotary systems. -
Page 29: Quadrature Mode
Quadrature Mode - Application Notes In a quadrature sensor, the two incoming pulses overlap. Pulses to input 1 will arrive before or after pulses to input 2, depending on the direction of movement. This is achieved by staggering the trigger zones for sensor A and B. They must overlap, so that one will lead the other in one direction, and vice-versa. -
Page 30: Logic Input Functions
Logic Input Functions The three contact closure logic inputs have default functions which are:- Contact closure 1 = Tare Contact closure 2 = Peak/Valley display Contact closure 3 = Reset You can re-assign these to include :HOLD, Nett/Gross value display, Memory page address 1, 2 or 4 (only if Multi-memory MEM option is installed). -
Page 31: Logic Input Connections And Front Buttons
Logic Input Connections and Front Buttons The previous page explained how to select the functions of the 3 logic inputs. You can connect remote contact closures or open NPN collectors to activate these logic inputs. The logic input provides a 5V DC signal. When you connect this to common, a current of 1mA will flow. -
Page 32: Signal Filtering / Averaging
Signal Filtering / Averaging You can adjust the filtering time constant to reduce the effect of noise or instability on your input signal. A larger FIL value will give a more stable display, but the response to signal changes will be slower. - Page 33 Filter Jump Value The Filter Jump value allows you to decide how the display will respond to a process step change. It does this by overriding the filtering, if the input signal moves by more than a chosen amount in one conversion. The Filter Jump default value is 10%. This means that for noise amplitude which has a peak value of less than 10% of the input range, filtering will be applied.

Page 35: Scale Factor Adjustment
Scale Factor Adjustment After you have calibrated your display, you can use the SCALE feature to make fine adjust- ments to calibration, without affecting the calibration itself. Example Changing volume units of measure from litres to Imperial gallons You could also use the SCALE to convert your readout from litres to imperial gallons, with- out affecting the calibration. -

Page 37: Menu Timeout Adjustment
Menu Timeout Adjustment The display has a default timeout of 60 seconds, to allow you sufficient time to refer to the manual between key operations. You can make this period shorter, if you wish, once you become more familiar with the setup method. - Page 38 Reverse Display Function (Mirror Image) If you need to be able to see a reflection of the display in a mirror or other reflective surface, for example in a simple heads-up system, or for drivers reversing into a bay, using mirrors only, you can set the display to show as a mirror image.
