The Pt100 terminal must only be connected to a Pt100 sensor by means of a shielded cable.
The cable shield must not be located on the plug housing in the event of any uncertainty
concerning the sensor ground, as this might result in measurement errors caused by double-ground
compensation currents.
-
The Rx measurement input must only be connected using a cable with individually shielded wires.
The maximum permissible capacitance here is 10 nF. The observation of this limit is particularly
important in the case of high-impedance test objects.
3.6 Operational test
After the RESISTOMAT
®
model 2329 is turned on, the following text is displayed for about 5 seconds:
Exception:
This text does not appear if a quick start has been activated in access menu (see
chapter 5.3.3.1)
3.7 Calibration
The RESISTOMAT
®
model 2329 is calibrated before delivery.
The measurement instruments used for this purpose comply with DIN ISO 9000ff standards.
The RESISTOMAT
®
model 2329 should be re-calibrated once every year or so.
Re-calibration is performed via the RS232 interface; this task should only be carried out by the
manufacturer.
Basic balancing of the individual measurement ranges is described in chapter 5.4.4.13 titled "Balancing".
3.8 Storage
Permissible storage temperatures lie between -10°C and 60 °C.
If the RESISTOMAT
®
model 2329 has been exposed to moisture during storage, ensure that it is completely
dry on the inside and outside before commissioning it.
No other measures are required for commissioning after storage.
