Resolution to 0.1 milli-ohm. 4-wire connection with ground(ground terminal is broken) All dials turn and unit measures on an ohmmeter- all switches and resistors are functional. Has stickers& wear& tear. Came from government/ military surplus.
ESI 801 dc generator detector. Lights up when plugged in as shown. No further testing performed. Will need cleaning& restoration. Or can be used as a parts unit. Originally government/ military surplus(has Navy cal lab stickers)
Complete ESI 701 Capacitance Measuring System. Consisting of model 707B Capacitance Bridge and model 861A AC Generator/ Detector. Frequency 20-20 KHz. Direct measure capacitance dials and deviation dials. Installed into an ESI rack. Has military cal lab stickers& sticker residue. Acquired years ago from government surplus and never put into service, so can't vouch for function or calibration.
Resistance range from 1 Ω to 1.11111 MΩ, Six decades, High-performance solid silver-alloy contacts, The ESI DB62 Dekabox In-Line Decade Resistor provides dependable long-term service in precision DC through audio frequency applications. Six decades of non-inductive. Precision, wire-wound fixed resistors are mounted in a low noise shielded aluminum housing. The input terminals and a case connected ground terminal are conveniently located on the front panel. The dials rotate independently through 360 degrees to simplify and speed settings. This allows for a coarse approximation and then precise finer steps to provide an exact resistance value. Accuracy over a wide range of ambient conditions is assured by the use of resistors with good temperature and power coefficients. Repeatability is assured by the use of switches that have multiple contacts ... moreof solid silver-alloy. The Dekabox resistance values are easily read from the large-numeral in-line presentation above the knobs. Resistance per step and current ratings of each decade are presented above the knobs for operator convenience and circuit safety.

Description ESI(Electro-Scientific Industries) SR1050-1M Resistance Transfer Standard 1 Megohm/step Description Based on a unique method for establishing known ratios. The ESI SR1050 standard utilizes a transfer technique that consists of switching resistance sections in parallel, series or series-parallel sections. An outstanding design feature is a structure in which the only insulation leakage paths(other than those within each resistance section) are from the external terminals to ground. This eliminates insulation leakage errors in the transfer of calibration from one resistance level to another using three-terminal measurement techniques. A specially designed lever switch provides a convenient means of switching into parallel and series parallel configuration without introducing insulation leakage errors. External shorting or paralleling ... morebars are not necessary. Each resistance section consists of precision wire-wound resistors connected in series. The reduced heat concentration of the series connection improves the thermal characteristics of a resistance element with an already low temperature coefficient Advantages of Transfer Standards In order to perform calibrations with a high degree of accuracy. Reference standards must be employed at every range or decade of the measuring or calibration instrumentation. Clearly, this can be difficult and costly since these standards must be highly stable and their precise values must be known with a high degree of certainty and sufficient resolution. To minimize the cost and difficulty, more practical means of performing such calibrations is to use transfer standards. ESI SR1050 Transfer Standards Basic Specifications Transfer Accuracy Limited only by short-term repeatability of resistance values. Typical repeatability 2 ppm, Long-Term Accuracy 50 ppm of nominal value, Temperature Coefficient 5 ppm/°C. Matched within 5 ppm/°C, Power Coefficient 0.05 ppm/mW per resistor, Maximum Power Rating 1W/step or 5W distributed over 10 steps. Or maximum voltage of 2.5

ESI Dekatran DT72A Standard Decade Transformer Electro Scientific Industries Military Surplus
For your consideration is an ESI model DB62 s/n 626004. There are six decades of resistors from 1 Ohms/step in the first decade through 100 kOhm/step in the sixth decade. The long term stated accuracy of the resistors from ESI's original manual is as follows: 1 Ohm/step 0.5% 10 Ohms/step 0.07% 100 Ohms/step 0.025% 1 kOhm/step through 1 MOhm/step 0.02% Cosmetically the decade box is in decent shape with normal scratches. Sticker residue, etc. The plastic number dial of the first decade has a chunk missing from it. There are cracks in each of the other dials but none are broken. I checked the value of each resistor using a Fluke 8846A meter and am listing the results below. The results are in% error from the resistor's nominal value. These checks were made to give you an idea of the resistor's values and should not in any way be ... moreconsidered a calibration check nor is the calibration guaranteed.
