The two displays can be used for a variety of purposes: The 1705 is a 41/4 digit meter with a scale length of 12,000 counts and a resolution of 10V, 10m and 0.1A. Combined with a high basic dcV accuracy of 0.04%, it provides measurements that are an order of magnitude better than most hand-held DMMs. The 1705 can measure and display two signals simultaneously. These can be two parameters of one signal (e.g. ac volts & dc volts) or two signals applied to different sockets (e.g. ac volts & ac current). The 1705 provides True RMS ac response which gives accurate measurements regardless of the waveform shape. The wide bandwidth attenuator provides high accuracy within the audio band and gives extended response to avoid errors when measuring switching waveforms. Measurements are normally ac coupled but, when required, the true RMS value of the ac plus dc components can be shown. Auto or manual ranging To show the selected range in addition to the measurement units (e.g. 100mA dc). To display a measurement in two different units (e.g. ac volts and dBm). To display the result of a calculated function (e.g. s value and % deviation). To measure and display two parameters of one signal (e.g. ac and dc volts). To measure and display two different signals (e.g. ac volts and dc current). The 1705 offers fully automatic ranging on all functions. Alternatively, ranges can be selected manually. Unlike other meters, the range value can be clearly shown on the secondary display avoiding any possibility of confusion. Mains or battery operation The 1705 can operate either from ac mains or from batteries (disposable or rechargeable). In battery mode it can operate for up to 80 hours. Frequency & capacitance Main display dc Volts dc Volts ac Volts ac Volts dc Amps ac Amps Secondary display ac Volts ac Amps Frequency dc Amps ac Amps ac Volts Signal inputs 1 2 1 2 1 2 The 1705 offers high accuracy frequency measurement (better than 0.01%) from 10Hz to 120kHz. It uses a reciprocal counting technique to give up to 0.01Hz resolution at 10 readings per second. The 1705 also incorporates capacitance measurement in four ranges up to 120F. More information The 1705 has a number of powerful built-in functions designed to make life easier for the user. Most of these functions make use of the dual displays to provide extra information. Smart functions for added power dB measurements AC voltages can be displayed in dB as well as voltage Built-in zero reference scaling enables voltages to be displayed in dBm relative to any required impedance. Power measurement in Watts or VA In addition to dBs, the 1705 can measure power in Watts or VA. For resistive loads the Watts function calculates V2/R for any load resistance between 1 and 10k, a particularly useful function for audio measurements. Linear scaling with offset This function enables a reading to be multiplied by a scale factor (A) and for an offset (b) to be added or subtracted. The VA function makes use of the dual measurement capability and displays the product of voltage and current. Automatic data logging This means, for example, that the electrical output of a transducer can be scaled to give a direct readout of the physical parameter e.g. temperature or weight. It is particularly useful with 4-20mA current loops. Limits comparison The 1705 can store up to 100 readings at any required time interval from 1 reading per second up to 1 reading every 3 hours. A simple recall sequence allows the readings to be scrolled onto the display whenever required. Alternatively results can be downloaded using RS232 or GPIB. This function enables the reading to be tested against high and low limits set by the user. The display then shows HI, LO or PASS in addition to the measurement result.

The T-Hold function freezes the display every time a new but stable reading is detected. This avoids the problem of trying to watch the test points and the display simultaneously. Alternatively, a simple Hold function is also available. Full safety protection The 1705 incorporates extensive protection against damage from accidental overloads on all ranges including 10 Amps. It also meets the stringent safety requirements of EN61010-1 for measurements up to 1kV (Cat. I) or 600V (Cat. II). Relative measurement The null function stores the current reading and subtracts it from future readings giving a `relative' display. The nulled and normal readings can be viewed together. A separate -null function retains an independent null value for resistance measurements enabling test lead resistance to be permanently nulled out. Percentage deviation ( %) This function enables the meter to display the percentage amount by which the reading differs from a nominal value chosen by the user. It is invaluable for measuring tolerance or stability. Min-Max storage The Min-Max function stores the highest and lowest values of a set of readings. This facility has many uses such as checking for power supply glitches, recording peak temperature excursions and avoiding `missed' readings when using the Logger function. As a result, tedious time related measurement sequences can be handled automatically without disrupting your work. Manual storage of readings is also available eliminating the need for paper and pencil when making a series of measurements. Storage can also be triggered from contact closure or the digital interfaces. Full bus control via RS-232 or GPIB The 1705 has an RS-232 interface as standard which can be used for remote control and read-back of measurements. As well as operating as a conventional RS-232 interface, it can also be used in addressable mode whereby up to 32 instruments can be linked to one PC serial port as part of a TTi `ARC' system. A GPIB interface is available as an option. The 1705 uses a true dual measurement, dual display technique licensed under U.S. Patent No. 4 825 392. Low cost meters incorporating two displays do not have the same functionality. Screen illustrations are at approximately 70% of actual size.
