Information for the tester
Low-Resistance Measurement and Continuity Check (R)
Measuring method: Current-voltage measurement as per
IEC 61557-4
Battery voltage: ≥ 5,5 V; max. 9 V DC
Nominal voltage:
≥ 200 mA DC
Short-circuit current:
Permissible overload: U = 600 V (measurement is not started)

Compensation of measuring cables up to 5 Ω possible.
Measuring Range Resolution
0,01...0,15...999 Ω 0,01-0,1 Ω
approx. 20 Ω
Internal resistance:
Measuring time: approx. 2 s incl. voltage pole change for resistive
specimen rising to max. 20 s for parallel inductances.
Permissible inductive
component: max. 2.5 H without influence on measurement result;
max. 5 H without damage
Permissible series-mode
≤ 3 V AC or DC, no measurement is started beyond
voltage:
this value
Continuity check:
Same as low-resistance measurement, continuous measurement without pole
change after pressing the key. Response threshold: At Rext < 2 Ω ±0.5 Ω audible
signal and „con" is displayed.
Resistance Zero Compensation (<o>)
The measured value stored in this function is automatically subtracted in all
resistance measurements (R , R , R)!!
