Description

Meter enters MN MX modifier with <numeric value> as the maximum value.<numeric value> can be a signed integer, signed real number without exponent, or signed real number with exponent. Autoranging is disabled. See "MN MX Modifier" in Chapter 3.

If <numeric value> exceeds the measurement range, an Execution Error is generated.

Meter enters MN MX modifier with present reading as minimum value. If already in MN MX modifier, meter displays minimum value. In MN MX modifier, autoranging is disabled. See "MN MX Modifier" in Chapter 3.

Meter enters MN MX modifier with <numeric value> as the minimum value. <numeric value> can be a signed integer, signed real number without exponent, or signed real number with exponent. Autoranging is disabled. See "MN MX Modifier" in Chapter 3.

If <numeric value> exceeds the measurement range, an Execution Error is generated.

Meter exits the MN MX modifier. The stored minimum and maximum values are lost, and the meter returns to the ranging mode and range selected prior to selecting MN MX modifier.

Note

When the MN MX modifier is selected, you can toggle between displaying the minimum and maximum reading without losing the minimum and maximum values stored.

Meter returns a numeric value indicating modifiers in use. 1 = MN, 2 = MX, 4=HOLD, 8=dB, 16=dB Power, 32=REL, 64=COMP.

If multiple modifiers are selected, the value returned is equal to the sum of the values of the selected modifiers. For example, if dB and REL are selected, "40" is returned.

Meter enters the relative (REL) modifier, using the value shown on the primary display as the relative base. Autoranging is disabled. See "REL Modifier" in Chapter 3 for more on the relative modifier.

Meter exits the relative modifier and returns to the ranging mode and range selected prior to selecting the relative modifier.

Meter enters the relative (REL) modifier, using <relative base> as the offset <relative base> value.

<relative base> can be a signed integer, signed real number without exponent, or signed real number with exponent. Autoranging is disabled.

If <relative base> exceeds the measurement range, an Execution Error is generated. See "REL Modifier" in Chapter 3 for more on the relative modifier.

Meter returns <relative base>. If the relative modifier has not been selected, an Execution Error is generated.
