_________________________________________________________________________________________________________________
(34) POTENTIAL OUTPUT GAIN switch
7-position switch for selecting the amplification for the signal at (27)
POTENTIAL OUTPUT (mV); range: x10 to x1000.
(36) ELECTRODE RESISTANCE TEST push button
Push button for activating the ELECTRODE RESISTANCE TEST. The
ELECTRODE RESISTANCE is determined by application of 1 nA square pulses to
the electrode and is shown in M at display 39. Function is indicated by the M
LED 37. The ELECTRODE RESISTANCE TEST works in OFF mode as well.
Hints: This function can also be used to adjust (51) CAPACITY COMP. (CC). The
POTENTIAL OUTPUT FILTER LOWPASS (26) should be set to 20 kHz and the
HIGHPASS (24) to DC.
With an amplifier with switchable headstage (ELC-SWI) the electrode resistance test works
also in enhanced (x100) current mode.
Note: If the ELC-03XS is equipped with the optional SEAL TEST circuit, the push button is
replaced by a three position switch. In the upper position the ELECTRODE RESISTANCE
TEST is carried out and in the lower position the SEAL resistance test is accomplished. The
value of the SEAL resistance is shown at the CURRENT display (45).
(37) M LED
LED indicating that the unit of the POTENTIAL/RESISTANCE display (39) is M.
(38) mV LED
LED indicating that the unit of the POTENTIAL/RESISTANCE display (39) is mV.
(39) POTENTIAL / RESISTANCE display
Display for the potential at the electrode in XXXX mV (1999 mV max.) or the
electrode resistance in XXX M (999 M max.). The unit is indicated by 37 or
38.
SERIES RESISTANCE COMPENSATION unit
The SERIES RESISTANCE COMPENSATION unit consist of (18) SERIES
RESISTANCE COMP. (%) potentiometer, (40) R
COMP. LED
