- Determine the polarity of the capacitor and completely discharge the
capacitor.
- Connect the black safety measuring line to the COM jack

, Hz
9
of the
teStFOX M-1.
- Bring the safety measuring lines into contact with the discharged capacitor
according to ist polarity and read the measured value on the digital display
of the teStFOX M-1.

8.7 Frequency measurement
( teStFOX M-1)
- Select the desired function (Hz) by means of the rotary switch
8
of the
teStFOX M-1.
- Connect the black safety measuring line to the COM jack
J
of the
teStFOX M-1.
- Connect the red safety measuring line to the jack for V,

9
of
the teStFOX M-1. Please observe the minimum sensitivity for frequency
measurements of the teStFOX M-1!
- Bring the safety measuring lines into contact with the measuring
points and read the measured value on the digital display
of the
teStFOX M-1.

8.8 Temperature measurement
( teStFOX M-1)
- Select the desired function (°C or °F) by means of the rotary switch
8
of the
teStFOX M-1.
- Connect the temperature measuring adapter and the temperature measuring
line to the COM jack (-)
J
and to the jack for V,
,
, Hz (+)

observing
correct polarity.
- Arrange the end of the temperature measuring line in the vicinity of the heat
source to be monitored. read the measured value on the digital display
of the teStFOX M-1.
See figure 11:
Temperature measurement
8.9 Voltage indicator
the voltage indicator function is possible from each position of the rotary switch.
No measuring lines are required as voltage indicator (non-contact detection of
an alternating field). The detector is located on the upper part of the device
behind the leD. By pressing the „VoltSensor“ key
5
, the display indication
disappears (if the display is switched on). if a phase voltage is localized, this is
indicated by an acoustic signal and a red leD signal
M
. An indication is made
in earthed AC current networks only! the phase can be determined by means of
a single-pole measuring line.
Practical hint:
interruptions (cable breaks) in cables lying around openly such as e.g. cable
reels, fairy lights etc. can be traced from the feeding point (phase) to the point
of interruption.
Functional range:
≥
230 V

8.9.1 Phase test
- Connect the red safety measuring line to the jack for V,
,
, Hz
9
of the
teStFOX M/ M-1.
- Bring the safety measuring line into contact with the measuring point of the
system part and press the „VoltSensor“ key
5
.
- if the red leD lights and if there is an acoustic signal, the phase of an
earthed AC voltage is applied to this measuring point (system part).
9. Maintenance
Before opening the TESTFOX M/ M-1, make sure that the de-
vice is free of voltage! Electrical danger!
Working on the opened teStFOX M/ M-1 under voltage must be carried out
by
skilled electricians only who must observe special precautions for the
prevention of accidents!
therefore, make sure the teStFOX M/ M-1 is free of voltage before opening
the device:
- First, remove both safety measuring lines from the object to be measured.
- then, remove both safety measuring lines from the teStFOX M/ M-1.
- Switch the rotary switch
8
to position „OFF“.
