Trace
Long-range recording as a diagram of the rate and current results.
Time scale:
Automatic according to the measurement period selected; one point per
measurement, recording length 240 points.
Corresponds to a recording length of 8 min to 60 h.
Value scale:
Rate -1 to +10 s, logarithmic scale.
Current 20 µA, logarithmic scale.
Otherwise, the parameters for rate/current measurement apply.
Battery
Measurement of the measurement voltage with 2 M
Ω
load resistor (No Load) and 2 k
Ω
pulse-like
load during 10 ms (Low Drain).
Additional measurement by pressing the start key with 100
Ω
load resistor for 1 s (High Drain).
Result display:
Voltage: No Load, Low Drain, High Drain.
Measurement range: 0 - 3.5 V, 10 mV resolution.
Accuracy: 0.5% of measured value ± 10 mV.
Graphical display:
No Load voltage, display range 3.4 V.
Fault display: Polarity and acoustic signal in case of wrong polarity.
“Out of measurement range” and acoustic signal if the measurement range is
exceeded.
Resistance
Measurement of the coil resistance as well as detection of short-circuit and break.
Measurement range:
