Negative resistance value on a DMM
QMy DT4253 displays "-40 ohm" in resistance measurement. Why does this happen?
A
Timer calibration of withstanding voltage tester
QI would like to calibrate the timer of the 3153. When I set the timer to 1s, it takes about 1.3s to confirm the output voltage. Is the unit defective?
A
Can I use the heat flow sensor with the LR8515?
QCan I use the Z2013 Heat Flow Sensor with the LR8515?
A
Strange analog (D/A) output from the PW3335
QI use the PW3335-02 by connecting its analog output to a data logger. However, the output value does not match the PW3335 display.
A
10ms sampling of the LR8431
QIs it possible to use the 10ms interval for all 10 channels on the LR8431?
A
Difference between the LR8431 and LR8432
QIs there any difference between the LR8431 and LR8432 other than heat flow measurement?

How to use the SM9002 Verification Fixture for Surface Resistance Measurement
QPlease advise on how to use the SM9002 Verification Fixture for Surface Resistance Measurement (option for the SM9001).
A
Measuring current using the DT4281 and 9010-50 (clamp)
QI would like to measure current using the DT4281 with the 9010-50 Clamp On Probe. How should I set the DT4281?
A
Effective measurement range of power quality analyzer
QThe voltage range of the PQ3198 is 600V only. Is it possible to measure a 690V circuit?
A
