Battery operated check/calibration unit An exclusive instrument for checking the accuracy of scopes, multimeters and counters. 1/ Check/calibrate the timebase period and Y channel volts/cm settings of oscilloscopes. 2/ Check/calibrate the frequency and amplitude of counters and pulse generators. 3/ Check/calibrate the voltage, frequency and resistance ranges of multimeters. 4/ Use it as a crystal controlled pulse generator. Thirtyfive frequencies spanning seven decades from 2MHz down to 0.0125 Hz! See table below Blue Flashing LED ON indicator On indicator flashes at 2Hz, 1Hz, 0.5Hz, 0.25Hz, 0.125 Hz depending on range switch setting. Ideal for checking the accuracy of oscilloscope timebases, counters and digital multimeters with a frequency measuring range. This section is composed of a crystal controlled square wave pulse generator and divider. Provides 35 different preset square wave pulse outputs via the 5 way range switch and a corresponding seven way switch. The output (via a 50ohm BNC socket) is HS-CMOS compatible and has a frequency accuracy of better than +/- 0.1% Seven gold plated outlets. Contains six precision 0.1% metal film resistors arranged in series. Use for checking the accuracy of the resistance range of digital and analogue multimeters. With the DC/Pulse switch set to DC, a 10 way switch provides fixed DC voltage levels from 2.5V down to 10mV with 1% accuracy or better. Uses high precision 0.1% components and a precision voltage reference. Output via a 50 ohm BNC socket. Use for checking the accuracy of the DC voltage range of multimeters and oscilloscope Y amplifiers. This facility is used to check oscilloscope Y amplifier accuracy at different pulse frequencies and amplitudes. You can select from thirty five frequencies at ten precise amplitudes from 2.5V down to 10mV pk. Output via a 50 ohm BNC socket. SUPPLIED WITH INSTRUCTION/SPEC SHEET. RUNS ON FOUR AAA rechargeable batteries. The batteries can run down quite substantially without effecting the accuracy.
