I have some T/RH sensors (Precon HS-2000V) and want to connect them to the DT 85. But I don't know how to connect the four wires.

I need to measure an analog voltage of +/- 5 Vdc. I know I need to set the channel 10:1 attenuator in order to do this. When I configure the input range to '30V Input' on my channel in dEX and save to the logger, I get the error message as seen in the attachment.
I've tried doing the command through the command window in dEX also [9HV(GL30V)]. Then it seems to be accepted, but when I apply a

Hi Support,
I am trying to send the follow data to the RS485 port in HEX: 68 04 00 04 08 by sending \104\04\00\04\08
however it appears that only 68 04 04 08 is sent, the 0x00 in the middle was not sent.
Is there a workaround for this?
Thanks very much for the help

Hi,
I am using the +5V output to power a humidity sensor, I have used the command +5VSW=1 and set the logger up so that the 12V subsystem is continuously powered. However when I run the logger, the +5V works for short scan times (5secs) but for 15min scans the +5V does not switch on and so the sensor gives a bad reading.
Does whether having the USB connected affect whether the +5V SW is

We want to use datalogger to measure two channels - load cell and strain gage simultaneously, with a schedule such that, the data is recorded on a switch press and not at a fixed time interval.

I feel a trigger on switch press should be "Trigger on rising transition

After downgrading our firmware to 9.10.4890 per Datataker tech support recommendation our DT85 (series 3) is going through resets about every four days causing the loss of data during the reset.

Currently we have two schedules running; one 15 sec and one 1 min. In the 15 sec. we read 12 analog and 4 modbus c
We have a similar issue with the logger stopping to respond to be read through Modbus TCP/IP.

I have contacted technical support in relation to this issue, but this is a more general question regarding current loops.
When you configure a channel for a current loop (as opposed to a current input), without any scaling, the logger should be 'reading' a 0-100% figure. This is related to the 4-20mA range of these current loop sensors. Is that correct?
If I have configured channels for

Hello,
I have searched high and low in the manual and FAQ without luck. The DT85 Series 2 has TWO power supply inputs for the switched excitation and shunt resistor. They are labeled exactly the same (EXT * and EXT #).
My question: Are these inputs tied together (is one EXT * electrically equivalent to the other)? Is one power input used for certain analog channels? If I am using switch

Hello,
I want to run the DT85 via USB, so therefore I need a USB-Driver. Unfortunately, the Driver on the page seems to be missing. Also, the dEX software platform, which I thought I could find is leading me to an "not found" page. Could you help me with that problems?

I have a dt85 whereby it is continually crashing and stops logging cannot be connected to, & front panel becomes non responsive.
the only way to get the logger back on line is to preform a reset and once this is done the logger reverts back to a much older date.

We have DT85G recently, and we need to connect to it 3-wires LVDT of monitran company. we did several attempts of connection and all these gave an error reading.
The LVDT features are stroke 125 mm , supply voltage =9 to 24 Volts Dc(regulated) and its connection details are RED for supply volts DC , Blue for 0 volts DC and green for output(0-5).

I need to connect several Multi function Energy meter to DT85 using RS485.
I have never worked before with modbus /serial communication.
I checked manual and says need to set profile etc. But silly question, where do i put this code ? as i have always used deX for making program so it was pretty straight forward.
Should i use Detransfer to put command or can it be done

We would like to measure at higher voltages to get more accurate readings. When using the attenuator howe
