SECTION II2.0.0 INSTALLATION2.1.0 Mounting2.1.1 The instrument is designed for mounting in a standard 19" wide rack and is also availablefor bench mounting. No additional modification to the unit is necessary for eitherinstallation.2.1.2 All units are supplied with handles and weigh only 42 pounds. The overall size is 7" high,19" wide and 15" deep, behind front panel.Power requirements are 117 VAC, or 230 VAC ±10%; 60 Hz or 50 Hz. Slideswitch, located on the rear panel, permits selection of 117 Vac or 230 Vac. Thechange to 50 Hz or 60 Hz is automatic.2.1.3 The unit is designed to be easily transported form one lab to another and to be in operationin less than one minute from turn on time.2.1.4 This unit is self-contained and needs no further unpacking other than connecting the power.2.2.0 Supplied Connectors, CablesAll instruments are supplied with a mating AC power cord.Nomenclature K-H Part Number Quantity1) AC Power Cord CAB008 1 ea.*******CAUTION*********UNUSED TAPS ON HIGH VOLTAGEOUTPUT TRANSFORMER MAY BE ASHIGH AS 1000 VOLTS!!!5 Win-man\<strong>4601</strong>.wpd
SECTION III3.0.0 OPERATION OF THE INSTRUMENT3.1.0 General setup3.1.1 Set the 110/220 switch on the rear panel. The power cord of the standard source should beplugged into any convenient outlet of 115 VAC or 230 VAC, 50-60 Hz.3.1.2 The level lights on the front panel will indicate the correct operation of the internaloscillators. If an external oscillator is used, it is adjusted at this time, until the green led isilluminated. If the internal oscillator is to be used, frequency selection should be made atthis time.3.1.3 The desired output voltage can now be selected be by use of the range and decade switches.The load is connected to the output terminals. The "operate" push button switch may nowbe depressed, which will apply the preset voltage to the output terminals.Important: For optimum performance in "external osc. mode" adjustments of leveland major (decade) frequency changes must be made with the unit in "STANDBY"red led on. An attempt to adjust the input level with the unit in operate may causedistortion in the output of the unit or an erroneous output voltage!!!3.1.4 It is good practice to make large voltage and load changes in the standby mode. Undersome conditions the above changes can cause over voltage of 15% of the desired output.3.1.5 In the event of an overload of 50% or a short circuit the unit automatically recycles itself to"standby" mode. Depressing the "operate" switch with the short or overload still present atthe output terminals will cause the unit to return to "standby" immediately. Below 10 V, ashort circuit can be maintained at a rate of approximately 50 mA per volt.6 Win-man\<strong>4601</strong>.wpd
