Tips & Know How Calibrating your Electronic Tripmeter for optimum results.An incorrect calibration setting produces an incorrect readout! NO Wheelspin! and NO Cutting Corners! Never assume that your last event or Motorway Test session set-up, is correct.At the Start of every event always recalibrate your Tripmeter to the organisers Test Distance. (who can guarantee what a measured Mile/Kilometre is? no one) If the Test Distance is greater than 1 Mile/Kilometre, use a calculator and simply divide the Test Result by the Test Distance. e.g.The Organisers specify a Test Distance of.05.50 Miles/Kilometres. (With the Tripmeter in Calibration Mode the Test Result is showing 37.29 which means it is 3729 measured units, which when divided by 05.50 = a Tripmeter setting of 678. Therefore set the switches @ 678 (3 switches or digits) or 0678 (4 switches or digits). If the Test is circular, e.g. 04.20 Miles/Kilometres, drive the Test Distance non-stop for 5 laps and then divide the Test Result by the 5 laps covered and then by 04.20 to give your correct switch settings. This produces a finer tuned Tripmeter and is well worth the effort. |
The Don Barrow 'Code of Practice' Organisers and Competitors - Tripmeter notes Please print this article in your Rally Regulations, so that all Competitors know you are using this system. All events whether Stage, Road or Regularity Rallies should adhere to a standard 'Code of Practice', so that the Competitor who also uses the same 'Code of Practice' can achieve a far better and accurate result.
When measuring an exact known Mile or Kilometre, it is imperative to use an Electronic Tripmeter set up in it's Calculation Mode - so that an exact Distance can be recorded and replicated in pulses per Mile or Kilometre. As an example, if an Electronic Tripmeter in Calculation Mode, records 1997 Pulses to the Mile, as against 01.00 Mile (Normal Running Mode measuring Miles) on the Tripmeter Display - you can clearly see that by setting up your new Test Distance in Calculation Mode, using the known 1997 Pulses, will be more accurate than using 100 units to replicate. Because Therefore it's imperative to use the Tripmeter in Calculation Mode. Get this wrong - especially on Regularity events and you will have a lot of disgruntled competitors to contend with. It's just as easy to get it right, as it is to get it wrong! Imagine a Competitor setting up their Electronic Tripmeter exactly to the Organisers set Measured Mile, which is incorporating an error, and then competing on a Regularity Section of 50 Miles in length. Their Timing would be 'way out' let alone having to adjust the Distances in the Road Book to suit all the Junctions etc.
