DIGITAL MΩ HiTESTER 3154 Safety Standards Measuring Instruments For the Laboratory to the Production Line Six Test Voltages from 25 to 1000 V The Model 3154 DIGITAL MΩ HiTESTER provides six selectable test voltages: 25, 50, 100, 250, 500 and 1000 V, in order to support a wide variety of tests to evaluate electrical and electronic components and equipment. Comparator and timer functions facilitate easy insulation resistance testing in accordance with various safety standards, and a complete external I/O interface is provided for efficient automated line testing. 1 Efficient Insulation Resistance Testing ✱ Insulation testing of electrical and electronic equipment Motors, printers, magnetic heads, etc. ✱ Insulation testing of electrical and electronic components Transformers, coils, switches, relays, etc. ✱ Insulation resistance testing according to various standards Machinery, medical equipment, home appliances, office equipment, etc. ✱ High voltage resistance testing Resistance measurements of components in actual operating circuits. ●Six Measurement Voltages Provided in a Single Unit Any of six measurement voltages can be selected for use in a wide range of applications, from electrical and electronic component testing to electrical and electronic equipment. The comparator can be set up for use with each measurement voltage. ●Storage for Ten Setting States Up to ten setting states can be stored for quick selection when testing for compliance with various standards. ●Easy Standards Testing Testing for compliance with various safety standards is simplified by using the comparator and timer functions for quick pass-fail judgment of minimum acceptable limits. ●Automatic Electrical Discharge Function The unit discharges any charge buildup on the measured object as a result of electrical loading. This electrical discharge function prevents the effects of one test from being carried over to a subsequent procedure. ●Remote Control Operations such as test start/stop and voltage selection can be controlled remotely, such as for start/stop control from a switching probe. ●Slow Sampling Selection to Minimize Instability Selectable fast (10 sample/s) and slow (1 sample/s) sampling rates are provided. Slow sampling minimizes instability when measuring at highly reactive test points.

Auto Range The range increments when the current range is exceeded by 2000 counts (except the top range). The range decrements when the current range does not reach 190 counts (except from the 2 MΩ range). 2 Full Support for Automatic Operation Both external I/O and RS-232C interfaces are provided to support fully automated operation. Measurement values can be tracked and recorded from the analog output, and printing is supported on an external printer using RS-232C. ●Record Variations using Analog Output This unit provides two types of analog output. Measurements are output linearly as voltages between 0 and +4 V DC, and insulation resistance fluctuations can be recorded. 1. Outputs each measurement range. 2. The maximum measurement range for each measured voltage is output between 0 and +4 V DC. ●Analog Output Terminal The maximum measurement range for each measured voltage: DC4V 0 0 200MΩ (25/50V) 2000MΩ (100/250V) 4000MΩ (500/1000V) ● Rear Panel Measurement Terminal (always connected to front panel terminal) ●RS-232C Connector Automatic calculation can be performed on a PC, and printing can be performed using the 9442 printer. 9442 Printer Printing method Paper width Printing speed Power source : Thermal serial dot printer : 112 mm : 52.5 cps : AC adapter 9443 , or supplied nickel-hydride battery (Charged through the 9443; printing capability approx. 3000 lines with full charge) ●External I/O Connector Pin I/O Signal Description 1•2 O INT.GND Connects to internal ground and power line ground lead 3 I EXT.COM 4 O FAIL LOW indicates Fail judgment Connect to ground of external device 5 O PASS LOW indicates Pass judgment 6 O TEST LOW indicates Testing state 7 I VOLT2 8 I VOLT1 VOLT0 Sets test voltages (including comparators) Sets saved test conditions from No. 1 to 7 9 I 10 I STOP LOW = STOP key 11 I START LOW = START key 12 I EXT.DCV Power supplied from an external device 13•14 O INT.DCV +5V DC internal power (100 mA max.)
