1. User s 700987 Manual Isolation logic probe The 700987 is a Isolation logic probe for DL716 Make sure to comply with the following safety precautions Not complying might result in injury or death WARNING Before using the logic probe be sure to read the DL716 s user s manual in addition to this one as it contains necessary precautionary information relevant to the probe s use AN CAUTION Applying a voltage exceeding the voltage indicated below may cause damage to the logic probe or DL716 At a frequency above 1 kHz damage may occur even when the voltage is lower than this voltage Maximum input voltage at a frequency of 1 kHz or below 250 Vrms except ACpeak is 350 V or less DC is 250 V or less e Each input terminal of the isolation logic probe is isolated from all other input terminals and the isolation logic probe is isolated from the DL716 e Make sure to turn off DL716 before connecting or disconnecting the 26 pin connector from the logic input connector e Do not stack the isolation logic probes during use Also allow enough space around the probes to avoid a temperature increase inside the probes Logic Input Connector Connect the logic probe to either of the logic probe input connectors the two connectors indicated POD A and POD B About the Logic probe Use the following leads to connect to the point of measurement e For measuring voltages of 42 V or less Measurement lead Model 366961 e F2. C input 50 VAC 50 Hi level 80 to 250 VDC Lo level 0 to 20 VAC Response time During DC input within 1 ms During AC input within 20 ms Input impedance approx 100 kQ Maximum input voltage across H and L of each bit 250 Vrms CAT I and II Maximum allowable common mode 250 Vrms CAT I and II voltage across input terminal H or L and earth Maximum allowable voltage between bits 250 Vrms CAT I and ID Withstand voltage across input terminal and earth 2000 VAC for 1 minute Isolation resistance across input terminal and earth 500 VDC 10 MQ or more Fuse location max rated voltage max rated current type standard H side of input terminal 250 V 50 mA time lag VDE SEMKO 1 Make sure the ACpeak voltage does not exceed 350 V and the DC voltage does not exceed 250 V when the frequency is 1 kHz or less 2 Because the fuses used by this instrument are all inside the case they cannot be exchanged by the user If you believe the fuse inside the case is blown please contact your nearest YOKOGAWA dealer listed on the back cover of this manual External Dimensions Unit mm 117 3 The dimensional tolerance is 3 unless otherwise specified However the tolerance of dimensions less than 10 mm is 0 3 mm IM 700987 01E
