Instrument Accuracy

[bill93]

That certainly is true of some manufacturers in some of their series. But I wouldn’t bet on it for all.

Surely it’s worth the time to find the manuals or google up the actual specs on each model.

I don’t know if that’s a good rule of thumb. I work at a Trimble retailer and for example, an S6 can be either a 1, 3, or 5 second gun. A Trimble model 5603 can be a 1 second gun as well…

Thanks, I have always thought that too simple given worldwide production. Find the manuals that should be fun.

Thanks

I have never heard of a Trimble 5603 model instrument advertised as a 1″ gun.

I was under the impression, based upon Trimble’s literature that the

model numbers in the 5600 series were 5601, 5602, 5603, and 5605, which corresponded to the angular standard deviations.

It may be entirely possible that Trimble would sell a 1″ gun as a 5603 in order to fill an order when there was a shortage of 3″ guns. However that would have to be backed up with the original certificate of compliance that contains the angular accuracy tied to the serial number of the instrument.

Seems too simple to be true to me as well. I think of the old Wild T-1, T-2, and T-3, T-3 being the highest-precision.

Many manuals for everything, can be found online these days. You might do a simple google-search with the word manual, and the model number. Some people even scan their paper manuals and upload them for others to find it seems, and good companies try to provide their manuals as well.

If you can’t find information like that on-line, without resorting to extraordinary means, you probably aren’t going to be able to get service and support for the unit either.

Both the 1100 and 1200 series Leica instruments did use the first digit to signify the precision. 1201 was a 1 second gun, 1103 is a 3 second gun.

That nomenclature was not used prior to that.

Bob,

I can clarify for the Leica world of total stations. The angular accuracy of the instrument was indeed the last digit of the model displayed on the instrument sticker on the instrument for the 300, 400, 700, 1100, and 1200 series of total stations. This made things easier because when you said you had a TCR 803 you knew it was a 3 second instrument with reflectorless (R in the TCR)

Now in the current lines of instrument every instrument will start with a TS (Total Station Survey) and such models that are a TM are configured for a monitoring type total station (Total Station Monitoring). So the mid-range instruments are the FlexLine total stations and have the models TS02, TS06, and TS09 but this has nothing to do with angular accuracies. The models just indicate the hardware configuration … for example the TS02 comes from the factory with a very basic keyboard and no bluetooth, TS06 comes with expanded keyboard and Bluetooth, TS09 comes with everything on TS06 but also has color screen and better on-board software. Each flavor also has different reflectorless EDM ranges available and can be ordered in different angular accuracies. The TS11 is a Viva series but is strictly manual but has Viva SmartWorx running on it and . TS15 models incorporate different motorization options…. and also the TS11 and TS15 have different ranges of reflectorless EDM’s available and each can be ordered in different angular accuracies.

Yes… quite confusing.

The part number of the instrument tells you what model the instrument is when looking at the angular accuracy and also the equipment ID sticker in the battery compartment. There is also an easy way to view the same information in the software once it is running.

I am not sure why Leica made these changes. I think it may have been easier marketing wise to split between models that are say a basic total station, advanced manual station, or robotic total station.

The new high-end total station only come fully loaded and at one specific angular accuracy – MS50 = 1 second only, TS50 1/2 second only, and TM50 = 1/2 second only. This may add to the confusion.

Tom,

I have a T-4 and a BC-4, both have 0.1 arc second precision.

I have a Sokkia Set 530R that is 5sec
The Set 230R is 2sec

Have to look it up these days with so many markers and models
