Omega Speaker Systems HH-23A - Manual (Page 5)

3
MAXIMUM COMMON MODE VOLTAGE: 42V peak to earth.
POWER: 9 volt transistor battery (NEDA 1604).
BATTERY LIFE, CONTINUOUS: 50 hrs typical, carbon-zinc; 100 hrs typical, alkaline;
200 hrs typical, lithium; 15 hrs typical, Ni-Cd (rechargeable).
BATTERY INDICATOR: Display indicates BAT when less than 10% of life remains.
DISPLAY: 5 digit LCD, 0.4" height. Polarity indication, and decimal point.
Annunciators
• Readout Parameter: T1, T2, T1-T2, SCAN
• Record Parameter: MIN or MAX (when viewing recorded data).
• Readout Scale: °F, °C
• TC Type: K, J, T
• Hold (when activated)
• Reading Trend:
up-arrow for increasing readings, down-arrow for decreasing
readings. Both arrows on for stable reading.
• Record MIN/MAX readings for T1, T2, and/or T1-T2; Flashing annunciator indi-
cates data being collected. Steady annunciator indicates data available, but not
being up-dated.
KEYPAD: 9 momentary switches with tactile feedback select;
• Power ON/OFF
• Readout: T1, T2, T1-T2, or SCAN
• TC type: K, J, T
• Readout scale: °F/°C
• Resolution: 0.1°/1°
• Display Hold
• Record MIN/MAX
• View MIN/MAX
• Stop recording MIN/MAX (first keystroke), clear recorded MIN/MAX (second
keystroke)
POWER OFF CONFIGURATION RETENTION: Instrument retains last selected;
• Readout: T1, T2, T1-T2, SCAN
• TC type: K, J, T
• Resolution: 0.1°/1°
• Scale: °F/°C
DIAGNOSTICS: Display codes indicate the following conditions:
• Low Battery: ‘BAT’
• Open Thermocouple(s): ‘OPEN’
• Invalid Keypad Entry: Momentary ‘E-1’
• Temperature Reading exceeds TC Rating: ‘E-2’
• Internal Hardware Fault: ‘E-3’ (consult factory)
• LCD Test: During power-up, all segments/annunciators turned on momentarily.
ELECTROMAGNETIC COMPATIBILITY: Add ±0.5% of range to accuracy specific-
tions for RF fields up to 1 volt/meter. Accuracy not specified for fields greater than
1 volt/meter.
DIMENSIONS, WEIGHT: 7.0" x 2.9" x 1.1". Net weight 10 oz.
