YHS-707 HART mode Process Loop Calibrator with Output 24V 0 -100% Span Check
Quick Detail:
• 0 - 20 mA or 4 - 20 mA default start up modes.
• Push button 25% steps for fast, easy linearity checks.
• 1 µA resolution for mA source, simulate and measure.
• 0-100% “span check” for fast confirmation of zero and span.
• HART ™ mode connects 250 Ω resistor in series with 24 V loop for compatibility with HART communicators.
• 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM.
Description:
