DC Specification: In addition to the availability that requires warm-up of 60
minutes, it must be set in 5/s speed rate (60/s speed rate for Continuity and
Diode), A-Zero on.
[2]
The entire range of measurement will pass the set range by 20% except the
tests of 1000 V DC, 3 A DC, 10 A DC and diode.
[3]
This specification applies to 4-wire resistance measurement, whilst it requires
using "REL" function for offset on 2-wire resistance measurement. 2-wire
resistance measurement will cause additional error of 0.2
Ω
if REL function is
not executed.
[4]
This specification applies to the voltage measured from input terminal. 1 mA
test current is the typical value. The change of current source leads to the
variation in buck of diode junction.
[5]
Accuracy is ± (DC Input ac DC Reference accuracy), where Input
accuracy = DC Voltage accuracy for the Input HI to LO (in % of the Input
voltage), and Reference accuracy = DC Voltage accuracy for the HI to LO
(Sense) Reference (in % of the Reference voltage).
[6]
The 10 A range of measurement is available for the terminals on front panel
only. Due to power factor resulting in temperature rise, 2 mA increment per
one ampere when input is greater than 5 A.
