AC AUTOMATIC INSULATION/ WITHSTANDING HiTESTER 3174 Safety Standards Measuring Instruments Featuring contact check functionality The effects of test lead wire breaks, erroneous test results caused by faulty contact, and fluctuations in test voltage caused by variations in the instrument’s supply voltage on withstanding voltage and insulation resistance testing are well known. The 3174 (3174-01) AC AUTOMATIC INSULATION/WITHSTANDING HiTESTER is a low-cost solution featuring contact check functionality as well as a stabilized power supply to prevent the reduced test reliability that can result from these issues. To streamline production line test processes, the HiTESTER also features configuration of test parameters via RS-232C (GP-IB) and reading of parameters from the EXT I/O interface. 2 2 NEW Improved Test Reliability ● Contact check function improves test reliability If a test lead wire were to break during testing with a tester that does not offer contact check functionality, defective test pieces would be judged to be non-defective. The 3174’s contact check function lets you detect test lead wire breaks and faulty contact during testing by sensing measurement issues in real time. Withstanding voltage tester The 3174 improves test reliability by monitoring voltage to detect lose leads during testing and faulty wiring during measurement. Voltage output Voltage monitor Withstanding voltage tester Voltage output Faulty contact *Break in lead Voltage monitor Voltmeter Voltmeter Contact check Test current Test piece If a test lead were to come lose during testing with a measurement device that does not offer contact check functionality, defective test pieces would be judged to be non-defective. Faulty contact *Disconnected lead *Since contact check is performed while testing is in progress, use of contact check functionality does not increase cycle time. Contact check Test current Test piece Fluorescent display tube The display uses a bright, easy-to-read fluorescent tube. DANGER lamp Flashes a warning during testing and whenever high voltage is present at the terminals. The DANGER lamp turns off when the voltage at the output terminals is no greater than AC 30 V or DC 60 V. 9613 SINGLE-HAND REMOTE CONTROL (option) 9614 TWO-HAND REMOTE CONTROL (option) External switch NEW Enables start/stop control by means of the 9613 SINGLE-HAND REMOTE CONTROL or 9614 TWO-HAND REMOTE CONTROL. (The 9613 and 9614 are optional.) ● Judgment output at forced stop The ability to obtain a judgment even after a forced stop increases testing freedom. Test mode selection Select from three test modes: 1.Manual test mode: W (withstand voltage testing) / I (insulation resistance testing) 2.Automatic test mode: W→I / I→W ● Ramp timer function The ramp-up initial value, ramp-up and ramp-down time parameters can be set independently. ● True effective value display NEW ● Continued analytical testing after FAIL judgments Test pieces can now be analyzed by means of detailed monitoring of the test current accompanying FAIL judgments. ● Eliminate the effects of supply voltage fluctuations ● Delay timer function 3 Safe, Automated Operation Convenient Safe ● Continuous full-auto withstanding voltage and insulation resistance testing The 3174 lets you set independent test conditions including test voltage for withstanding voltage and insulation resistance testing, and you can perform these tests continuously. Press the W→I key to automatically perform withstanding voltage followed by insulation resistance tests, or press the I→W key to automatically perform insulation resistance followed by withstanding voltage tests. ● Interlock function Signal input from an external device such as an automatic tester can be used to disable output and prevent testing, ensuring safety during automatic testing and other uses. GP-IB (option) Enables remote control. RS-232C Contact check Enables remote control. LOW: A break in the lead is determined to have occurred when the check current is not detected. HIGH: A break in the lead is determined to have occurred when the contact check measurement voltage falls outside the range defined by the upper and lower thresholds. (Connectors are locked in place as shown on the left to prevent the leads from being disconnected.) Power cord inlet *Requires an additional pair of 9615 HIGH-VOLTAGE TEST LEADS.
