EZ-Dial™ Knob
Turning the EZ-DialKnob to adjust the output up or down. Fine adjustments can be made by turning the
EZ-DialKnob. Coarse adjustments can be made by pressing and turning the EZ-Dial™. New values can
be stored into the HI and LO EZ-Check™ positions by pressing down on the EZ-DialKnob until “STORED”
is indicated on the display.
EZ-Check™ Switch
The EZ-Check™ Switch has three positions: HI, DIAL, and LO. Its position is shown at the left edge of the
display with “HI” and “LO” indicators. The output is adjustable in all three positions. The EZ-Check™
Switch allows user-selected values to be stored in the HI and LO positions when used in combination with
the EZ-DialKnob.
To store new EZ-Check™ value(s):
1. Dial the display to match the desired stored outputs for the HI or LO positions.
2. Press down on the EZ-DialKnob until the confirmation message “STORED” appears.
3. Recall the values by moving the switch between HI, DIAL, and LO.
Operational description: When returning to previously set EZ-Check™ positions, the DIAL position always
recalls the last output value it was dialed to. The HI and LO positions will recall the last STORED value,
NOT the last output value it was last dialed to.
Hint: For faster calibrations, the product has been designed so the position of the switch can be felt. This
tactile feature allows continuous monitoring of the device being calibrated without looking back at the
Model 520/521 display. This is also useful in poor lighting or under difficult operating conditions.
