The TRIO FET VOM VT-108 is a highly-stable P type electronic voltage-resist-ance meter, employing field effect transistors, provides functions for memorizing the measured voltage or resistance values. We sincerely hope you to make the most of the VT-108 through careful operation of the set as instructed hereunder in this manual. FEATURES □ Function provided to memorize measured values temporarily-enable user to read out measured values after completion of measurement, □ Wide range of 0.01 ~ 1,500 V for DC voltage. □ Wide frequency characteristic ranging from 20 Hz to 5 MHz for AC voltage. □ Use of adaptor enables user to operate this set from an AC 100 V (117, 230 V) source. Switching of the set from the DC to the AC sources or vise versa may be accomplished by merely replacing a plug. D Use of RF probe (optional item) allowed for user without replacing it with the probe attached to the set.
