Position the RESISTOMAT® resistance measuring device so that enough space is left behind the back panel to ensure proper ventilation of the black heat sink. The output of the ventilation channel shown in Fig. 1.2 must not be obstructed. Enough space should also be allowed for the connection of interface cables. The device weighs 28 kg and is contained in appropriately shock-resistant packaging. Unpack it carefully and check whether any contents are missing. The standard scope of delivery includes: - a type 2304 resistance measuring device, - a mains cable, - a copy of this handbook. Check...

Installation The measuring amplifier (analog section) of the device is connected internally with the equipment grounding conductor as shown in Fig. 1.l. Fig. 1.1.: Ground conductor connection Normally, this INTERNALground is used. It is advisable to use a seperate, EXTERNAL ground only for networks which are particularly prone to interference.This also applies to measurements on objects with single-end grounding, like motors. In order to avoid ground loops here, the reference potential of the measuring circuit should be connected directly with the neutral point of the test unit.(seeChap....

Installation Power supply s .? ! -W The standard RESISTOMAT@is designed to operateat a mains voltageof 230„ + 6%- 10% and a mains frequency of 45 - 65 Hz. 115„, is available as an option (conversion is only carried out by the manufacturer; it is not sufficient to simply switch the voltage selector shown in Fig. 1.2). For this reason, it must be checked whether the voltages specified on the type and voltage plates correspond with the local mains voltage, before the mains voltage is connected (Fig. 1.2) and turned on (Chap. 2.2). The adaption of the device's internal time base (for...

Installation Line Power fuse s The two line power fuses each rated at 2 A (both with medium time-lag) are located behind the panel with the voltage inforrnation, inside the mains connection module (see Fig. 1.2). The fuses are changed by inserting a screwdriver into the notch underneath the upper edge of the mains socket, lifting the plate with the voltage information slightly, and pulling out the fuse-insert. ATTENTION: After a fuse has been changed, the fuse-insert must be pushed into the mains module in the correct manner (mark on housing facing arrow with the desired mains voltage)....

Maintenance General Information In principle, the RESISTOMAT does not require any maintenance by the user. If any repairwork becomes necessary, it must only be carried out by the manufacturer. The device complies with the relevant VDE (Associaton of German Engineers) specifications and postal interference suppression regulations. Enquiries Shipping instructions Customer service The manufacturer strongly recommends accompanying technical enquires with the relevant serial numbers. Only then is it possible to determine the technical model (including the software version) and thus ensure a...

The measuring unit of the high-precision RESISTOMAT® 2304 automatic measuring and testing device operates on the principle of an advanced 4-wire design shown in Fig. 1.3. The voltage drops when current is applied are measured not only across the test unit, but also across an internal reference resistor. Both voltage drops are used to calculate the quotient, which is multiplied by the characteristic value of the reference resistor in order to determine the ohmic value of the test unit. This procedure eliminates contact and transition resistances and is advantageous in that measurement errors...

A measured value results from the computational combination of 2 * 4 single measurements from a measurement cycle and comparison with the internally stored reference value. In this context, a distinction is always made between BIPOLAR and UNIPOLAR measurements of ohmic or inductive resistances (see Chap. 4.5, V.1). The resulting measurement cycles are illustrated in the following Figures 1.4,1.6 and 1.7: A1) BIPOLAR measurement of ohmic resistances R (see Chap. 3.1.2, V.6) t. A meaW = Wait M = Measurements U = Switch over E = Settling Fig. 1.4: BIPOLAR measurement of ohmic resistances The...
