8.4.1

DC measurement (CH1 and CH2)

!
Use measuring leads for measurements smaller than
60 VDC, 30 VAC or 42 VACpeak only.
Property Value/Range
Measuring range 200 mV — 60 V
Accuracy of CH1 ±0.75 % of measured value,
plus ±0.25 % of measuring range
Accuracy of CH2 ±2 % of measured value,
plus ±0.5 % of measuring range
Resolution 100 µV — 100 mV
(depending on measuring range)
8.4.2 Measurement of AC and rms value
(CH1 and CH2)
*)
Property
AC frequency range
Measuring range
AC accuracy at 100 Hz
rms accuracy at ≤ 100 H
Resolution
The measuring ranges in measurement modes "U" and "I" are
*)
specified as peak-to-peak values. Consequently, the digital
display box is "grayed out" if the set measuring range is briefly
exceeded (overload).

WLAN

Standard: IEEE 802.11g (54 Mbit/s), compatible with
IEEE 802.11b (11 Mbit/s), data encryption: OPEN, WPA,
WPA-PSK, WPA2, WPA2-PSK, WEP (64/128/256 bits),
antenna: -3dBi.
Radio link
KTS 340 to PC/laptop
Workshop environment with clear view
of access point
In vehicle interior with vehicle door or
window open and engine running
The range of the WLAN varies considerably.
20–40 m can normally be achieved indoors and up to
100 m outdoors.
Under adverse conditions the effective range may only
be 10–15 m or even less.
The KTS 340 automatically adapts the transmission
rate in the WLAN to the transmission conditions. In the
event of a poor radio link the data are transmitted
more slowly than with a good link.
