Connection of a multimeter to be calibrated (current range) to calibrator's output terminals
Optional current coil can extend the calibrator's current range to 1000 A. The coil can be used for calibration of
both DC and AC ammeters. The clamps of the ammeter must be positioned in angle 90
the current coil, no steel or other magnetic objects must be present in the vicinity (50 cm) of the current coil, as
they would deform the magnetic field and cause big calibration error.

Counters and oscilloscopes

The calibrator can be used for basic calibration of the frequency ranges of multimeters and simple counters. The
calibrator provides the following functions:
calibration of frequency functions up to 20 MHz using squarewave signal. The function is activated by
pressing F direct mode button and selecting HF mode. Frequency can be set.
check of input sensitivity from 1 mV to 10 V in the frequency range up to 100 kHz. The function is activated
by pressing F direct mode button and selecting PWM mode. Frequency, amplitude and duty cycle can be set.
calibration of time period using squarewave signal whose period can be set up to 10 s, with selectable duty
cycle. The function is activated by pressing F direct mode button and selecting PWM mode. Frequency,
amplitude and duty cycle can be set.
The instrument to be calibrated connects to FREQ connector using BNC/banana cable.
