dear Sir,

one of customers is using dt800 for resistance measurement.
recently we are facing the following problem;
measured resistance values are lower than actual e.g. 260 Ohm is measured while actual is 350 Ohm.
test command generated following:

pl advise,

Hi gpradipta,

Could you perform another TEST without any sensors?
If it still shows some fail specially other than lithium battery then you need to send the unit back for service.
Please use dataTaker support email for further corresponding if you want to send the unit back.

Best regards,
Rudy Gunawan
