Annunciators
The annunciator line has seventeen possible indications, shown below. All
display for a few seconds during the power–on sequence. Subsequently the
annunciators light to indicate the following meter states:
•
* (“sample annunciator”)– Turns on during a measurement.
• Hi–Z - For DC voltage measurements in the 100 mV, 1V or 10V ranges,
an input impedance of >10 GW is configured.
• OComp - For resistance measurements in the 100W, 1 kW and 10 kW
ranges, offset compensation is enabled.
• ManRng - For the selected measurement function, auto ranging is
disabled (a fixed meter range is selected).
• Tri g - The single triggering mode (from the front panel or rear trigger
terminal) is enabled, and the multimeter is in the “wait–for–trigger”
state.
• Hold - The reading hold function is enabled.
• Remote - The multimeter is in the remote interface operational mode.
• Error - A hardware error or remote interface error has been detected.
• Null - For the selected measurement function, the null feature is
enabled.
• Shift - The Shift key has been pressed.
• Math - Either the dB or dBm math feature is enabled.
• Stats - The statistics math feature is enabled.
• Limits - For an applicable measurement function, the limits math feature
is enabled.
• Rear - The multimeter will recognize input connections made at the rear
panel terminals (the Front/Rear switch is set to Rear).
• 4W - A 4–wire resistance or temperature measurement function mode is
selected.
• - The continuity test function is selected.
• - The diode test function is selected.
