a. Performance Check
(1) Connect multimeter to CAL 5V output. If multimeter does not indicate between
49.75 and 50.25 mV dc, perform b (1) below.
between .9975 and 1.0025 kHz, perform b (2) below.
(3) Press FREQ pushbutton to 1 MHz position (in). If frequency counter does not
indicate between .9975 and 1.0025 MHz, perform b (3) below.
