settings
Impedance 1 high limit 1.000 kOhm to
1.000 MOhm
(> Impedance 1 low

200.0 kOhm When Impedance 1
is “low*.”
In the case of
“high,” use the
value of FINE limit
for impedance
1 in SENCOM
diagnostic criteria.
Impedance 1 low limit 1.000 kOhm to
1.000 MOhm
(< Impedance 1 high
limit)
1.000 kOhm
Impedance 2 high limit 1.000 kOhm to
1.000 MOhm
