Measurement Conditions
WIRING Key
Press this key to display the menu for selecting the wiring system, setting the efficiency equation,
selecting the independent input element configuration, and setting the delta computation (option).
ELEMENT Key
• Press this key to select the input element that you want to select the measurement range for. The
selected input element changes each time that you press ELEMENT.
• When you select the wiring system, input elements that are assigned to the same wiring unit are
selected at the same time.
SHIFT+ELEMENT (ALL) Key Combination
Press this key combination to collectively set the voltage range, current range, or external current
sensor range (option) of all the input elements that satisfy the following conditions.
• The input elements are the same type (5 A or 50 A input elements).
• The valid measurement range settings are the same.
Press ELEMENT again to configure settings for individual elements.
▲ and ▼ Keys
Use these keys to select the voltage range, current range, or external current sensor range (option).
The ranges selected with these keys are valid when the AUTO key described below is not illuminated
(when the fixed range feature is being used).
AUTO Key
Press AUTO to activate the auto range feature. When this feature is active, the AUTO key illuminates.
The auto range feature automatically sets the voltage, current, and external current sensor ranges
depending on the amplitude of the received electrical signal. Press AUTO again to activate the fixed
range feature. The AUTO key turns off.
EXT SENSOR Key
Press EXT SENSOR to illuminate the EXT SENSOR key. While the WT1800 is in this state, press
the current range's ▲ and ▼ keys to select the external current sensor range that is used when the
WT1800 measures the output from the current sensor. Press EXT SENSOR again to turn off the EXT
SENSOR key and enable the selecting of the current range for direct input.
SHIFT+EXT SENSOR (SENSOR RATIO) Key Combination
Press this key combination to display a menu for setting the external current sensor conversion ratio
for each input element. These conversion ratios are used to convert current sensor output to current.
CONFIG Key
Press this key to display a menu for setting the valid measurement ranges for the voltage range,
current range, or external current sensor range (option). You can also set the measurement range to
switch to when a peak over-range occurs.
SHIFT+CONFIG (DIRECT/MEASURE) Key Combination
Press this key combination to display a menu for setting the display format of the external current
sensor range.
