GOSSEN METRAWATT GMBH 7
Frequency settings of 29 Hz and greater can only be selected
in a limited fashion.
Note!
☞
The following error messages may appear:
“HiCurr” (high current – current at overload limit)
where I
max.
= 18 mA, “0ut 0l” and 3 acoustic signals
(out of limits – limit value violation) where I > 30 mA.
The simulator is switched off.
Attention!
!
In this operating mode interference voltages must not
be applied to the calibrator jacks.
In the event of operating errors, such as the short-
term application of a high interference voltage, the in-
strument/calibrator is protected by a replaceable
fuse F3, see chapter 12.3.
5 Resistance Simulation [Ω]
Resistance can be simulated by means of 2-wire connection
within the following range: 5 … 2000 Ω.
➭ Connect the DUT with the measurement cables as
shown.
➭ Select the Ω calibration function with the rotary switch.
➭ Setting the simulation value:
The decade (i.e. the position of the digit to be changed) is
selected with the $! keys, and the respective digit is
set with the #" keys.
Note!
☞
The following error messages may appear:
“HiCurr” (high current – current too high) where
I > 4.5 mA and “LoCurr” (low current – current too low
or polarity reversal)
where I < 40 µA (i.e. open jack sockets).
Attention!
!
In this operating mode interference voltages must not
be applied to the calibrator jacks.
In the event of operating errors, such as the short-
term application of a high interference voltage, the in-
strument/calibrator is protected by a replaceable
fuse F3, see chapter 12.3.
After applying the measuring current it takes a maximum of
30 ms for the calibrator output to adjust to the specified
resistance value.
Incorrect measured values may result in conjunction with
DUTs which do not have a steady measuring current (e.g.
scanned measuring inputs) if measurement has already been
started during setting time. The calibrator cannot be used for
such objects.
