I am trying to setup a DT800 for a service engineer to use. The best way I can achieve this is to use activX in an Excel spread sheet I am using burst mode to collect data.

The problem I have is that it is very difficult to connect to the logger when in Burst mode. Using activX in Excel is impossible. Is there anyway (i.e a small program that could be run) that I can send a halt command to t

Dear Roger,

I don't know the true meaning of gain lock. For example , when the amplitude of signal is 2V, what is the effect when using GL1V?

Thank you

Dear Roger,

I find histogram channel option included in statistical. But I can not find in software Delogger, what is the problem? Besides, I want to measure temperature using PT100, but in Delogger, PT100 is not included, only PT385 and PT392.

Therefore, I have to program using Detransfer, am I right?

Dear Roger,

On page 51 of DT800 user's manual , It enumerates the sampling speeds for each channel, when one channel is sampled as voltage(NC)and voltage(corrected), there is no much difference. But when channels sampled simultaneously becomes 5, great changes take place.

Could you explain the reason? Besides, as for voltage(VNC), the sampling speeds between 1 channel and 5 channels are

Dear Roger,

I am puzzled when I read the section"Data Storage Capacity-Readings" on page 78 of DT800 user's manual.

It says when the schedule contains one channel, the readings per MB of DT800 storage is about 14500, while 2, the readings is 25800. Could I induce that DT800 storage capacity is improved while the number of channels per schedule increase? If so, Why?

Could you do me

Dear Roger,

I want to know the method to measure frequency. For example, how can I measure the frequency of sine wave? Could you tell me the concrete wiring configuration?

Thank you

Dear Roger,

I have a question, how to get the data stored in DT800? That is, I want to get the data of some job, 1,i.e., While DT800 was disconnected with my PC.

Thank you!

Dear Roger,

I have a problem now. That is, the realtime data can't display in chart window, while they can display correctly in other windows.

Problem comes up as follows, I measure AC volt in normal mode with scan rate of 200HZ, i.e. RA5T,display in chart window is normal, then I change the rate to RA10T.

Then, data couldn't display! I close the project, open it again, but it doesn'

Good morning,Roger,

I want to know whether DT800 could measure AC signals.

Thank you !

When using channel variables, does the DT800 allow the use of compound if statement e.g.

IF (1CV=2 && 2CV=7){[3CV=1CV/2CV]}
If so what general form does it have

Is there any limitation in the performance of the DT800 if a Compact Flash card is used instead of a PCMCIA ATA card? CF cards seem to be less expensive and easier to obtain.

I realize, of course that a card adapter will be needed but these are only a few bucks each. I had proposed to buy a SanDisk 512MB CF card. Any known problems with this manufacturer? If yes, can anyone kindly recommend

Is it possible to use burst mode to sample thermocouple outputs and when completed have stats option/command return the average value.

I'm interested in logging the returned burst readings, only the average. If so what the schedule look like.

Hi, I do not have RS-232 port on my laptop. Can I use LPT1 or LAN port for communication with DT800?

Thank you.

Hi,

I have a problem with the transfer speed of data to a memory card during a burst. When the logger runs without a memory card inserted it takes about 10 sec. to log the data but if I have the memory card inserted it takes about 2min 50sec.

If the burst has been run without the memory card inserted until the internal memory is full it only takes a couple of seconds to transfer the data

Can any one help me. I have the following program loaded on to a DT800

I want to use our DT800 to send texts via a GSM modem. I want to send a string of the form "Fault at Time t1, Left Tension = x N, Right Tension = y N" Where t1 is the loggers current time and x & y are logged values.

I've set up the alarm. I know how to talk to the modem. How do I get Delogger to set up an action to send this string?

Cheers,

Hi, When i am using a analogue level to trigger a burst is it then possible to use the level channel 1VNC as a working channel.

My burst looks like this:

RA1+E;BURST(1000,1000,LEVEL,10,0S) LOGONA GA
1VNC("Relay",LEVEL>2500)
1V("Relay")
2V("Valve")
3V("Pressure")
I tried to add the W to the line

1VNC("Relay",LEVEL>2500,W)
When I do that i get an error when I send the progr

Hi. After i have configured the unit i will only be able to connect via Ethernet(Telnet or FTP) is it possible to control and retrieve the logged data via Telnet or FTP?

I am recording temperature inputs to my DT800 on an hourly basis. Is there a way to trigger the logger to only record the temperatures every hour when the feeder to the unit is running. Right now it records hourly 24/7?

One of our 800's seems to have developed a problem with reading BGV(6W) inputs. There seems to be a loss of resolution resulting in an increase of noisy data.

The method of input appears to be OK as the 800 module was swapped onto the terminals with our 2nd 800 showing no problems. Any theories?

Thanks,
Mitch
