" Warnings and precautions to avoid personal injury and multimeter damage are listed in this section and in section "Operating Instructions ". ■ All inputs are protected against continuous overload conditions up to the limits 'of each function's stated input protection (see Specifications).
320b.qxd 7/21/00 5:46 PM Page 5 Messen an Bildröhrgeräten (hohe Spannungsspitzen) ■Unsersuchen Sie Gerät, Meßkabel, Verbinder, usw vor jeder Messung. Beschädigte Teile nicht verwenden o ■Meßspitzen and Stromkreis während der Messung nicht berühren Sich selbst isolieren! ■Bei Strommessung, Multimeter immer in Serie mit Schaltkreis verbinden -- Nie in parallel mit Schaltkreis.
320b.qxd 7/21/00 5:46 PM Page 6 OVERLOAD INDICATION Whenever an input signal is larger than the range selected, an overload symbol "1" will appear in the display. This indication is normal in the OHMS range when the leads are not connected to anything or when the measured value is higher than the selected resistance range. In all other situations, take immediate steps to remove the cause of the overload condition.
320b.qxd 7/21/00 5:46 PM Page 7 PREPARATION FOR USE - UNPACKING Your shipping carton should include the multimeter, one TL-245 Probe Set (one black, one red), one 9V battery (installed), three fuses (two installed and one spare inside the case), plus one TP-255 thermocouple (HD110T only).

320b.qxd 7/21/00 5:46 PM Page 9 INITIAL CHECKOUT Connect red test lead to the V-W Input Connector and black test lead to the COM Input Connector. Turn the Function/Range Switch to the 20MW position. With the two test lead tips separated, the Digital Display should read 1 (overload). Turn Function/Range Switch to each W position. With test lead tips in contact, the display should read 0 in each position. (00.1 or 00.2 in 200W position due to test lead resistance).
320b.qxd 7/21/00 5:46 PM Page 10 MEASURING PROCEDURES General Procedures: ❶ When connecting or disconnecting test leads to a circuit, always first turn off power to device or circuit being tested and discharge all capacitors. ❷ If magnitude of signal is not known, set switch to highest range and reduce until satisfactory reading is obtained. ❸ Strictly observe the max input limits.

D • Gleich und Wechselspannungsmessung ❶ Rotes Meßkabel mit V-W Eingang verbinden and schwarzes mit COM. ❷ Funktionsschalter auf gewünschten Bereich in DCV oder ACV stellen. ❸ Meßspitzen mit Meßkreis verbinden - in parallel zur Spannungsquelle. ❹ Meßwert ablesen (automatische Polaritätsanzeige bei DC Messungen).
320b.qxd 7/21/00 5:47 PM Page 13 d'autres formes d'onde. La valeur efficace de signaux non-sinusoïdaux ou déformés est obtenue directement et avec une plus grande précison avec les modèles RMS225 ou HD160 de Wavetek. DC AND AC CURRENT MEASUREMENT (seeFig. 2) ❶ Connect red test lead to the A Input for current measurements up to two amperes or to the 10A input for current measurements to ten amperes. Connect black test lead to COM input Connector.
320b.qxd 7/21/00 5:47 PM Page 14 RESISTANCE MEASUREMENT (See Fig. 3) All resistance ranges on the multimeter are low-power ohms which allow accurate measurements of in-circuit resistance. ❶ Connect red test lead to V W Input and black test lead to COM Input. ❷ Set Function/Range Switch to desired W position. ❸ Connect test leads to circuit being measured. ❹ Read resistance value on Digital Display.
